Re: [BackupPC-users] Data integrity checks

Hi Jan,

the file based deduplication is baed on checksums, so if a new file is stored with the same name and file-size it will only be stored as a new file if the checksum is different. If the checksum is different, a hard link will be used to point at the already existing copy.

But these checksums are used for deduplication only and as far as I know there is no additional integrity check, for example on a restore.

Honestly I don’t think it is really needed. I’m using a ZFS volume for backuppc which has build in block level checksums for integrity.

Probably this is an option for you?

Kind regards

Andreas

Hi,

does backuppc do some data integrity checks on stored files or files
to-be-stored? Something like regular md5sum checks.
