That's why I prefer and recommend a combination of online or nearline storage for primary backup purposes and nearline or offline storage for long term storage. One example is using Amanda to back up nodes to virtual tapes on a big ZFS raidz2 and then writing those dumps to tape every few weeks. Another is copying Btrfs snapshots to hard drives in a eSATA or USB dock that's only turned on during copies and then rotating out these disks to a fire box. And the rule of thumb: figure out how much time you can afford to spend reconstructing lost or corrupt data. Run backups at least that often. -- Rich P. _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
