The backup server should have information about when a particular backup was made, it should be able to prune based on backup date without having the ability to read any of the data inside the backup.
- pierrebai 7y agoI assume the backups are incremental, so you cannot just toss old encrypted files without losing backed up files.
- zaarn 7y agoWorse, it's deduplicated, using a similar algorithm to git. You can forget old backups and theoretically that could be done without decrypting but deleting the actual data will require a decrypt.
- rcthompson 7y agoThis doesn't make any sense when the backups are deduplicated (or incremental). A given file/block/whatever unit of data isn't uniquely associated with a single backup.
