I have a 1TB external USB drive that I use for backups - using sbackup I have just found that a file I overwrote cannot be restored from backup - not critical, I can live without the file, but on testing none of the files can be restored!! I have been playing with back in time as an alternative: first time it failed over permissions on some files which I changed (or excluded from the backup) It has now failed again (log below)
Any ideas?
It's corrupt, has failed, dead, broken, a usb drive no-more. I'd try this: Unplug it.Coult to 10 & plug it back in again. Also make sure it's powered properly - preferably via an external PSU.
Run badblocks on it: badblocks -c 256 -s /dev/sdbif that reports errors, then it's probably toast. You can look at using ddrescue to recover it and/or other tools, but you'll need another 1TB drive to ddrescure it onto. Depending on how toasty is it, you may be able to mount it read-only and recover some data, but really, bin it.
(After ruling out USB errors, cabling, and the other obvious stuff)Also - why are you using ntfs? If you're backing up Linux stuff, use a Linux native format - ext3 or ext4 ...
And test that you can restore your backups before having to rely on it.. Gordon -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
