Using Bareos as an enhanced rsync

[David Pearce]

We have a well-functioning Bareos set up backing up 120 Windows and Linux servers to tape.

We want to start using FreeNAS / ZFS as the destination now instead of tape. But to take advantage of ZFS snapshots, I need to store the individual files on the ZFS server instead of a single backup file.

Can Bareos store the backed up files and attributes as individual files?

[Marco van Wieringen]

No it cannot nor do I envision it will ever do so. I also fail to see why
zfs snapshots would need this writing to individual files. You can setup
things on top of ZFS as VTL with fixed size volumes. Whenever things are
stable e.g. no backups are running you can snapshot ZFS and use that as
"stable" recovery point. I would however still use DiskToDiskToTape for
your really important bits as I've been using ZFS for as long as it
exists e.g. Jan 2006 in Solaris 10 and never lost a bit but snapshots
are eventually not a way to make sure admin error wipe out full backups.

I also advice anyone who currently uses tapes to think again about ever
abandoning them. A recent talk at our Open Source Backup Conference
done by IBM shows why you should really take a good look at tape.

Then again everyone also still runs filesystems other then zfs and get
bitten by silent data corruption etc. because disks just give back random
garbage or just some random sector of data.

Thanks for the excellent video. I totally understand that tape has way more life and upgrade possibilities than hard drives. If I have to guess, I'm expecting SSDs to replace ALL spinning disks in 3-5 years.

However, tape has kind of a problem satisfying one of my primary backup tenets: Off-site storage. With tapes, this takes a contract at something like Iron Mountain and paying for a courier. With a SAN/NAS type solution, I replicate to an off-site location automatically, with no addition "human" involved all over the internet.

Tape served us well, but my company needs a solution that takes less "human" interaction.

I'm open to ideas.
