Backups Disappearing?

[gboudreau]

Here's what I understand from that log:

The backup ended on or just before 23:15:31.
The backup was writing to a file named quarkbackup7_3_20101.tib
When the backup completed, that file was renamed (probably by the backup software) to remove the ending 1: quarkbackup7_3_20101.tib > quarkbackup7_3_2010.tib

When GH tried to work on that file, it seems it's not able to read the file size, owner, or permissions (see the errors about the filesize, fileowner, filegroup, fileperms that says 'stat failed').

Execute the following on your HDA (as one command):

Code: Select all

echo '<?php $file="/var/hda/files/drives/sdb1/Quark_Backup/quarkbackup7_3_2010.tib"; var_dump($file); passthru("ls -la " . dirname($file)); passthru("ls -la \"$file\""); var_dump(filesize($file)); var_dump(fileowner($file)); var_dump(filegroup($file)); var_dump(fileperms($file)); ?>' | php

This should check if the file still exists, and try to output it's size, owner and permissions.

Also, please verify the backup file still exists. If it does, make sure the filename really is "quarkbackup7_3_2010.tib"

Also, please execute this, to check what other GH tasks are queued, after the one that can't seem to get executed:

Code: Select all

sqlite3 /var/cache/greyhole.sqlite 'select * from tasks order by id' | fpaste

Thanks.

I'm about to follow your instructions, I just want to answer your questions first.

Yes, the backup ended at 23:15 or so.
I don't remember the initial name of the file, but I have seen that extra "1" on the end in previous backups.
The final name of the backup was quarkbackup7_3_2010.tib.

The backup file does not exist in the share anymore: it was deleted promptly at midnight.
the size of the backup when it existed was 49 Gig.

By the way, this happened when I tried other backup software too, not just TrueImage.

hi, result of the echo:

The result of the next command:

No text to send.
[root@AMAHI ~]#

OK, I was expecting the file to still be present, since you didn't manually remove the transaction with ID 0.
Can you please re-do a backup, and re-execute the above commands (both echo ... and sqlite3 ...) once the backup is complete?
Allow just enough time after the backup is complete for Greyhole to try to process it (a minute maybe), then run the commands.
At that point, I think the backup file would still be there, and that's what I want to see: why can't Greyhole correctly work with that file, if it's really there.

Thanks again for your time!

[bbuzzard]

hey, no, thank you for your time!...You are adding the value to this process, not me!

I'll run the backup later today or this evening. I'm going on holiday for a week starting tomorrow, so I won't be near my hda until July 10 or so, but I'll keep up to date on the forum.

[bbuzzard]

OK, 1 minute after backup:

root@AMAHI ~]# echo '<?php $file="/var/hda/files/drives/sdb1/Quark_Backup/quarkbackup7_3_2010.tib"; var_dump($file); passthru("ls -la " . dirname($file)); passthru("ls -la \"$file\""); var_dump(filesize($file)); var_dump(fileowner($file)); var_dump(filegroup($file)); var_dump(fileperms($file)); ?>' | php

Arg! I forgot to tell you to replace the filename in the "echo ..." command with the new filename of your backup file!

Code: Select all

echo '<?php $file="/var/hda/files/drives/sdb1/Quark_Backup/quarkbackup7_4_2010.tib"; var_dump($file); passthru("ls -la " . dirname($file)); passthru("ls -la \"$file\""); var_dump(filesize($file)); var_dump(fileowner($file)); var_dump(filegroup($file)); var_dump(fileperms($file)); ?>' | php

Or, for today, I'd guess the filename would be:

Code: Select all

echo '<?php $file="/var/hda/files/drives/sdb1/Quark_Backup/quarkbackup7_5_2010.tib"; var_dump($file); passthru("ls -la " . dirname($file)); passthru("ls -la \"$file\""); var_dump(filesize($file)); var_dump(fileowner($file)); var_dump(filegroup($file)); var_dump(fileperms($file)); ?>' | php

[bbuzzard]

My bad...I should have known.

I'm going to be away for a while. I'll do it with the right filename asap when I get back.

[bbuzzard]

Hi, back from vacation...I didn't get a chance to rerun the command with the correct filename. I can't seem to put together 30 uninterrupted minutes on the computer lately.

However, I did a bit of experimenting. I prevented the date from being appended to the backup filename, and I split the file into CD size files. Aside from not having the date in the name and getting 84(!) files due to the split size, the backup survived the night and greyhole is still running without error. That's good news, right?

I'll try to run through it again with a single file and no appended date and see if it survives. When I get time, I will do it with the command you asked for 1 minute after.

Thanks!

[gboudreau]

I found another user with similar problems (warnings about fileowner / filesize / etc.)

Can you show me the result of this command?

Code: Select all
