Hey folks, I can see there''s been a fair bit of discussion on this topic in the past, I wondered if anybody has any feedback on the best way to do this? We''re looking to use ZFS and Samba to serve files to our windows clients, which means we''ll be using NFSv4 permissions. While the data will be replicated to a number of servers, and we''ll be making extensive use of ZFS snapshots, I''m very concious that all of these copies of the data are still stored on ZFS, and could potentially be vulnerable to a ZFS bug. While it''s a risk, it''s a very low one, so we''re considering simply archiving everything to tape once a week. The plan is to use a tape autoloader and dump the whole 1TB pool out to it. I''m not concerned about restoring individual files, or restore performance, in fact our sole restore requirements are: - We want to be able to restore to a separate ZFS pool for testing - We also want to be able to restore to a UFS file system (just in case) So it''s not a complex backup regieme, but as I''m a complete Unix newbie so could really do with some advice on how suitable the options I''ve found are: Tar ======I understand we can use tar to stream the data to tape. There appear to be have been concerns about NFSv4 permissions with tar, am I right in my belief that these are now resolved? How easy is it to schedule backups with tar with e-mail notification if anything goes wrong? Amanda =======Amanda seems to be highly recommended, but I have no clue how it actually runs the backups, or whether it''s compatible with ZFS and NFSv4 permissions. Does anybody out there have experience of using Amanda? Is the added complexity actually worth it given our straight forward requirements? This message posted from opensolaris.org
