Mozy is corrupting my backups

Jamie Kahn Genet - 25 May 2008 08:54 GMT
I've managed to backup only a few GBs so far due to the extremely slow
upload speed I'm getting with Mozy.
However I've tried restroring a few files already backed up - a jpeg, a
PDF, and a few text clippings. The jpeg and the PDF were restored ok,
but the text clippings all had their contents stripped away by Mozy :-(

I'm now extremely concerned. Has anyone else experienced this? I'm not
sure I trust Mozy with my other files. I mean - how on Earth do you
screwup the backup of a text clipping?

TIA,
Jamie Kahn Genet

By not copying the resource fork.  This is very alarming.

Yes, well. I thought so! :-\ Heh. I'm going to run a few more tests
tonight and see what it does to other similar types of files.

So it appears Mozy doesn't support resource forks.  Yuck...

Do they advertise that they support Macs?  If so, I'd say that
classifies as false advertising, and is reason enough to demand your
money back.

I wouldn't do it either, for the same reason.

Um. Something slightly backwards here. The risks of *NOT* backing things
up remotely would seem higher.

Unless perhaps you are concerned with the privacy of your data. In that
case, yes, the risks of remote backup are higher. Mozy claims to have it
encrypted, and you can even use your own key if you like. But yes, there
is certainly at least more risk there than if you don't let the data out
of your house at all. But I didn't think that was the kind of risk you
are talking about.

Or perhaps you omitted an "only" in there somewhere. (In fact, I'm
almost certain that is the case). I wouldn't have my only backup be one
that I was trusting someone else with. I agree there. but the "only"
there is really, really, important. If you use an online backup service
as an additional level of backup, then that can only lower your risks of
losing data; it can't increase them. While that might seem so obvious as
to not merit saying, I *have* seen people misunderstand things that
seemed even more obvious to me.

(For example, I help my wife with her math tutoring center. One lady
signed up her daughter at our $150/month rate and then was surprised
when she got the $150 bill for the second month. She apparently didn't
understand the "per month" part and thought that the $150/month for a 12
month commitment sounded like a lot better deal than $175/month for 6
months. Sigh.)

I'm currently using Time Machine, SuperDuper, and Mozy, for 3 separate
backups. Perhaps slight overkill, but I was using SuperDuper and Mozy
before going to 10.5. When I went to 10.5, I wanted to leave my 10.4
backup untouched for a while (and SuperDuper took a while to support 105
anyway), so I got a separate new disk for TM.

Who said anything about not backing up remotely?

I said I will not rely on an online company for my remote backups.

There is no assurance of any kind they will be there tomorrow.

There is no assurance of any kind they are not scanning my documents.

There is no assurance of any kind they are not sharing my information
with others.

There is no assurance of any kind they are running reliable systems.

True, but while they are there, I have off-site backup in case of
disaster.  And I do have my local backups.  Something about eggs
and baskets.

> There is no assurance of any kind they are not scanning my documents.

Unlikely as mine are encrypted before they leave my system (OK
there is a chance they have left a backdoor in the encryption
their client does for me, but if anyone discovers this, it could
result in lawsuits that might just make the company disappear).  
The company here is EMC (Mozy was purchased by EMC).

Again it is encrypted.  If they are sharing, the others that might
break that encryption have easier ways to get my information.  It
is called a search warrent, or one of those national security
letters.

> There is no assurance of any kind they are running reliable systems.

Well if you think EMC makes lousy storage devices there are some
fortune 500 companies that would like to know what you know.  Then
again it is possible the just have a bunch of Linux boxes in the
back room with a few 1TB disks attached :-)

And for me, this is all in addition to my own local backups.  And
since I'm paranoid, that is done using 3 different backup tools
(Time Machine, SuperDuper!, and rsnapshot), with 1 in my home, and
2 on different disks on my office workstation (which I own and
control).

If you don't like EMC, then how about Amazon.com via JungleDisk.  
Or CrashPlan.com

Amazon's S3 with JungleDisk is what I'm now trialing. I'm not sure why
Amazon wouldn't be trusted. Certainly more so than Mozy's parent
company.

I will absolutely be getting my money back from Mozy - this is
unacceptable. BTW - has anyone duplicated my problem? With all the
Leopard/Intel Mac troubles I have I wouldn't be too surprised if this
turns out not to be Mozy's fault. Not a lot surprises me nowadays when
it comes to the MacOS.

If you want to trust them with your data, that's your call.

I trust ME with my data. Full stop.

I especially don't trust a company to hold my data in the United States
of America where it is subject to their laws, zero expectation of
privacy, and the ability for anyone who has it to sell it to anyone
else.

Not a f.cking chance.

I find it comical that a company would claim Macintosh compatibility and
totally fail to support resource forks! They claim to have had a beta
testing phase recently - this never came up?!  Very strange...

In my limited test, I got my Resource Fork back.

But I'm a sample of 1.

I suggest macsupport@mozy.com be contacted about this problem.

And in my test I did get my Resource Fork back.   I suggest
contacting macsupport@mozy.com to see if they can identify the
problem you are seeing and correct it.  'macsupport' has been very
helpful in the past.

Did you use the "restore files" option on the Mozy menu?  I don't know
how else it can be done, but I'd like to be sure we actually did things
the same way.

Jamie, please contact Mozy support about this.  I did and they've been
very interested, since Mozy is supposed to support resource forks.  
They've asked for some specific information from my Mozy installation to
help them diagnose it.

The more people who report the problem, the more likely it is to get
fixed.  So get in touch with them and tell them what you're seeing.

Heya Tom.

NP - I reported it at the first hint of trouble, but I'm not getting
anywhere yet, other than to prove that both the Mac restore app and the
web restore option both result in the same damaged text clippings.

Still, I'll give their techs a chance to look into this further :-)

Yes, I used the Mozy -> Restore Files...
I created an empty directory to restore the file into.

Are you at all concerned that the permissions and creation dates of the
restored files are not the same as the originals?

In a perfect world, I would prefer identical dates, but in my
personal situation, Mozy is for disasters.  I have local backups
using Time Machine to a networked iBook as my home server,
SuperDuper! to my workstation at work, and select files via
rsnapshot to a different disk on my workstation at work.

So Mozy is my worst case situation backup.  Not having original
dates is minor compared to what must have happened to loose the
above 3 backups :-)   And having my one of a kind data, family
pictures, music, family videos, etc... is far more important to me
than the original file dates.

However, I may mention this to Mozy.  You never know, user
feedback can result in future improvements to a rather good v1
product.

MozyHome for Mac has supported backing up and restoring resource forks
since our 0.9 release in December 2007. If you are having problems,
please upgrade to the recently released 1.0 version or contact
macsupport@mozy.com. We want to resolve any problems you are
experiencing with resource forks.

> Are you at all concerned that the permissions and creation dates of the

Restoring the correct creation date should already work. Restoring the
correct modification date will be fixed soon. Restoring permissions is
not on our roadmap for the near future, but we're planning to support
that as soon as we can.

How about ACLs (both explicit and inherited) and extended attributes?

Extended attributes, file ownership and file permissions are all

been put off a bit. But we'll get there.

Dan, I appreciate the personal attention from Mozy here and the concern
over the issue, but it's clear that Mozy 1.0 is failing to support
resource forks at least some of the time.  I've had Mozy fail to restore
resource forks and I've only ever used version 1.0.

I've been going back and forth with Mozy support and so far all they've
been able to tell me is that it should work, and that the log files I've
sent them indicate that it did work.  Still, restoring test files fails
to bring back the resource fork.

I was contacting the main support address-- "support@..." from the Mozy
web site.  Would it make any difference if I contacted "macsupport@...",
or would that just get me to the same people?

Do you have the developer tools installed?  If you do, you might
try using

   /Developer/Tools/GetFileInfo  original_file
   /Developer/Tools/GetFileInfo  restored_file

Is the output identical?  You want to look closely at the
'attributes' as "Capital" letters indicate the attribute is set,
and "Lowercase" letters mean the attribute is not set. eyes and
ells can be confusing so check carefully.

   /bin/ls -le@ original_file/rsrc
   /bin/ls -le@ restored_file/rsrc

to see that the resourced fork was not there, as well as show if
there are any extended attributes.

And finally the differences between

   /usr/bin/stat original_file
   /usr/bin/stat restored_file

Based on feedback from Dan, I suspect there will be some
differences.  But what may be more useful, is giving those
differences to macsupport@mozy.com

My previous experience with support@mozy.com vs
macsupport@mozy.com was totally in favor of macsupport.  It seemed
when sending mail to 'support', they did not seem to grasp that
when I said Mac OS X, that I was not using Windows.  Using
macsupport, they always seemed to have a Mac clue.

The attributes are identical-- "avbstclinmedz" in both cases.  This
check demonstrated that the restored file is also missing its type and
creator codes, though that's probably not a huge concern on a
disaster-only backup.  At least it doesn't represent lost data.

I don't think "e" and "@" really make sense on the resource fork--
extended attributes and ACLs only apply to the file itself.  Using those
flags on the original and restored files (without "/rsrc") shows the
original having com.apple.ResourceFork and com.apple.FinderInfo
attributes, and the restored file having none.  A plain "ls -l" on the
resource fork path shows a nonzero resource fork on the original, and
zero length on the restored copy.

> And finally the differences between

The only significant difference is that the original file shows 336
blocks allocated, while the restored file only has 96.  That's
consistent with the results of "ls -l", so it doesn't really add
anything.  [Other insignificant differences included things like the
files having different inode numbers, which is expected.]

I've already sent the "ls" numbers and the file sizes shown in the
Finder to "support@...".  The other commands don't seem to be adding
much, unless there's some detail you have in mind that I didn't think of.

  Log files indicate up load or restore? I am wondering if it gets
there, but not necessarily back when you restore. That would certainly
be consistent with both them and you being right, at least from
available information.

From what I could see, the log file includes pretty much everything Mozy
does.  I found both backup and restore operations listed.  I also sent
them all of the files found in /Library/Application Support/Mozy/, which
includes a bunch of sqlite database files and some other stuff.

Regardless, they keep telling me that resource forks are supported,
while their software is not restoring them.  It doesn't matter to me if
a file was backed up if I can't restore it to its original state.

It may be that their client software for Mac does indeed support
resource forks, but the resource forks are being broken at the back end.

if their servers are running something like Windows Server, then
depending on how the resource files are being stored on their servers,
it's entirely possible that they are doing something to clobber them.
For example, some Windows backup software destroys Mac resource forks on
files placed on the server using Services for Macintosh, and some file
copy utilities do likewise.

I would not be at all surprised to learn that your Mac files are being
sent to live on a Windows or Linux server and something Mozy's doing on
the back end is destroying them.

Tom,

Would you feel comfortable zipping up and emailing me a file that
isn't working for you? Zipping it should preserve the resource fork
for me to experiment with.

The "support@" and "macsupport@" email addresses both go to our
Support team, but I believe the alternate email address helps them
classify things better.

Will do, the file in question is an image that's on my web site anyway.

I just restored a file from Mozy which contains a Resource fork.  
I got the resource fork back.

Original:
ls -l BinHex4 BinHex4/rsrc
-rwxrwxr-x   1 harris       0 Jul  4  1986 BinHex4
-rwxrwxr-x   1 harris    7565 Jul  4  1986 BinHex4/rsrc

Restored:
ls -l Mozy/BinHex4 Mozy/BinHex4/rsrc
-rw-r--r--   1 harris       0 May 26 10:53 Mozy/BinHex4
-rw-r--r--   1 harris    7565 May 26 10:53 Mozy/BinHex4/rsrc

I would suggest contacting macsupport@mozy.com and see if you can
resolve the issue you are having.  I have found that the
'macsupport' email address has been very responsive.

Personally, I'm keeping Mozy as a one leg of my backup strategy.

    As a Clueless User (r) and not a Power User (tm), how would I know
which of the file(s) would contain a resource fork and how would I find
out if the resource came back. I also would suppose I should save the
restored file to a directory different from the original so I don't mess
something up.

He just showed you how to do it in the post to which you replied:

    ls -l BinHex4 BinHex4/rsrc

That's a terminal command. 'ls' is the command, and '-l' and the path to
the file (plus /rsrc) is the path to the file. So you can do this to
find out if a given file contains a resource fork:

1. Open a terminal window.
2. Type:  "ls -l " (without quotes - note the trailing space)
3. Drag any file into the terminal window to get the path.
4. Append (type) "/rsrc" to the end of the path.
5. Press Enter/Return on the keyboard.

Any resources (if they exist) will be listed in the output.

Just a slight clarification:

You can supply multiple paths to the 'ls' command. Above, these are two
individual paths:

    BinHex4
    BinHex4/rsrc

The first path is the path to the data fork of the file (the default for
the 'ls' command). This causes 'ls' to print information about the data
fork.

The second is the path to the resource fork of the file. This causes
'ls' to print information about the resource fork, if one exists.

Typo correction:

That's a terminal command. 'ls' is the command, and '-l' and the path to
the file (plus /rsrc) are command-line arguments.

I never said I don't back up my data.

Why not?  That's a big risk.

I'd be interested in hearing what kind of off-site backups you guys do.  
Is there any online approach you'd consider to be secure enough to use?

My off-site backups consist of a set of VXA2 tapes I store in a
fireproof safe off site. I rotate backup sets once a week, and recycle
(erase) them every two months.

I move my laptop between work and home, and back up to external hard
drive in both locations.

No, simply because the online backup can go away at any time and are
not under my control.

My strategy is similar to Dave's. I maintain both SuperDuper! and Time
Machine backups at both home and office locations, taking my MacBook Pro
almost daily to each location.

Right now the only off-site backups I trust are the DVD-Rs I store at
work and family's places.

Think KATRINA --  we lost one studio down to the foundation.  Had back ups
on site and across town (both totaled)

Only thing that saved us in the short run was off site (way) on line back
ups.

We do have out of state hard copy back ups but those are not easily
accessed.

Of course, your money back might be $0. (You can do up to 2 GB with the
free account.)

I'd also like to see a little more verification that they don't
correctly do resource forks. While it does seem like a plausible theory
to explain the observed behavior (I don't know what these text clippings
are and whether the data in question might be in resource forks), it
seems a rather large jump from "these files didn't restore right and
that might indicate a problem with resource forks" to "demand money
back."

It seems to me that somewhere in there a few steps got omitted. That
might include such things as

1. Verifying whether resource forks were indeed the problem and, if so,
whether it is actually all resource forks or just some subset.

2. Checking with the vendor's support (which might also help address
question 1).

3. Trying alternate ways of doing the restore (which vendor support
might plausibly also suggest). There are two different options, which
might well behave differently if there is a bug in something like that.
(Well, there's a 3rd option, but getting them to mail you a restore
cd/dvd costs money and I wouldn't do that just for an experiment like
that).

I've been quite happy with Mozy, including about 8GB of stuff
sucessfully restored after my daughter's hard disk died. But it is true
that I have very few, if any, files that have important stuff in
resource forks. It is plausible that I might not have even noticed a
problem with resource forks.
