I'm new to Lustre and am investigating what would be required for production. One of the things that we would require would be backup of the MDS and OSS data.
For the OSSs, from what I can see, this can be achieved on a per-volume basis using LVM and snapshotting. However, I feel uncomfortable with this approach and would prefer something where I can restore an individual file from backup if lost. Is there another way other than find with mtime to find the list of modified files in the file system ? For the MDSs, I cannot see how to back up an online MDS. If I do a split mirror without quiesce and backup the ext3 file system of the split-off mirror, I get an inconsistent state of database. I've seen various references to Amanda based systems but I've not been able to find the code that implements it so I could evaluate implementing the same thing with our TSM system.
