Hi all,

I have a question...

I tried restoring a backup to my system - it kept on failing with aborted by signal=PIPE.
I have a feeling it may have been related to corrupt files within the hardlinks, since when I tried restoring using tar, the tar files were not readable, and the zip files didn't have as many files in as I would have expected...

I didn't seem to be able to resolve that, so I wiped the system (keeping the home directory in tact), and rebuilt the server.
Now, unfortunately, the software I use to run the file server decided to delete my home directories when I restored the configuration...
Go figure...
So now, I'm really worried because I think that I will have lost about 100GB of data that I believed was backed up...
Anyway, I'm trying to restore now, but the tar files are still coming up as unreadable...

I guess if there are problems with the data, there's probably nothing that can be done?

How does backuppc check the consistency of the data once it's been added to the pool?
I know that it only backs up the data once, but how does it make sure that the data is in a valid state?
Is it checksums? If so, then I guess it can't be a corruption error...
... but I don't get why I would be finding directories of 3000 files showing only 1500 in a full backup...

Can anyone help? Any support would be greatly appreciated...
I've got all the coursework from a Masters and a PhD on there!
