Could anybody share her/his experience in backing up FreeNAS box to a tape drive please? Is it possible with ZFS, is it worthy and in what circumstances? Can I do ZFS replication to a tape drive?
If you use LTO6 and an autoloader then tapes aren't impossibly terrible (and you can get up to 40TB capacity uncompressed), but enough bad experiences with old tapes and trying to recover data really leaves a bad taste in one's mouth. Of course, you could probably build a second FreeNAS appliance as a replication target for the cost of the tapes, autoloader, HBA, and backup software. :)Tape support isn't expected anytime in the future. Tapes aren't generally useful at the massive scale ZFS is designed to operate at, so it's kind of useless except for small scale builds. But that's not what iXsystems and TrueNAS is all about.
A member of my extended family who works for a corporation dealing with obscene amounts of data told me that they use large-room-sized robotic tape systems for backup -- but which specific tape technology they use I have no idea.Did you read the comments on the article from slashdot? So many people had reasons why they moved away from LTO a long time ago and some had fairly detailed stories of it.
LTO is dead, whether anyone has realized it or not. The limitations LTO has (such as recovery speeds) cannot be easily fixed when pitted against a backup from hard drives.
I worked for the government, and we had similar backup hardware. The thing is, the scale you are talking about (and what I saw) is far beyond the size the forum typically refers to.A member of my extended family who works for a corporation dealing with obscene amounts of data told me that they use large-room-sized robotic tape systems for backup -- but which specific tape technology they use I have no idea.
