-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello everyone,
we've been using BackupPC for a long time now and have been happy with it ever since. Recently we have replaced the underlying storage file system with ZFS, which is mounted on the BackupPC machine via NFS. We're using both ZFS compression and ZFS deduplication with good results. (Hint do everyone planning to do the same: don't even think of trying that without a fast SSD- or DRAM-based ZIL device or without disabling the ZFS intent log, should you be courageous enough). Now with ZFS already doing deduplication, we've come to the conclusion that BackupPC's pooling mechanism is essentially pointless and a waste of resources. So we simply tried moving the /pool dir to a different location where BackupPC cannot access it, making sure that BackupPC also couldn't create a new /pool dir on its own. So far, this seems to work well: - - Backup jobs still work as expected - - BackupPC_link jobs fail (as expected) with a mkdir BackupPC/pool: Permission denied error - - however, as all files are still available in the respective BackupPC/pc directories, restoring seems to work flawlessly The obvious question: Is this a good idea, or will it break BackupPC at some point? Is anyone doing the same? And: Wouldn't it be nice to have this "non-pooled mode" as a configurable option for BackupPC? With ZFS becoming more and more popular, this could be interesting for other users as well.
