mds: efficient revert to snapshot
Added by Thomas Mueller over 13 years ago.
Updated almost 5 years ago.
Component(FS):
Client, MDS, kceph
Description
Use case:
Not so lucky user has deleted <think of many GB/TB data> of valueable data. Copying back from the .snap dir takes very long, restore from tape even longer.
Solution:
ceph provides a tool to replace the "live" directory with the snapshot content within a few seconds.

There's no RADOS support for reverting to an older snapshot so I don't see this getting fixed in any near-future time-frame. Closing this.
