We don't know if this backup is extra icing on the cake. Yes it's a week of restore, but it still might be entirely dispensable; e.g. 1 of 2+ glusterfs georep slaves and at least one of the others is XFS based. > I guess xfs is the standard recommendation for big-data sizes and it is > said to be long past the "better have a UPS" days, or of course the > default ext4. XFS is now the default filesystem for RHEL 7 and Fedora 21 Server, likely also for Fedora 21 Cloud.
