As a general rule, unless the ext3 file system experiences a crash that prevents it from writing data to the disk, it won't experience any problems that can be corrected by fsck unless the drive is unreliable (or controller, or memory, etc.) I'm not suggesting you not do it, but it's probably better to just reboot into single user mode and fsck the filesystem if this is what you want to do. That being said, xfs and/or jfs would be better choices for a filesystem, for both speed and reliability. -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

In theory, storing the job queue over a shutdown shouldn't be tough (it should just be a matter of writing a construct to a file, and reading it in on startup).

Hello, I plan to periodically e2fsck my /var/lib/backuppc. I want to write a bash script which check if BackupPC_dump is running. If not, it will stop backuppc, unmount the device and run e2fsck -fp $device What is about BackupPC_link? Should I check for this process too? There are further processes for which I should wait before unmounting the device? Thanks Matthias -- Don't Panic -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
