cephfs-snap - create CephFS snapshots periodically
cephfs-snap cephfs-snap [hourly|daily|weekly|monthly]

CEPHFS_SNAP_HOURLY Integer, number of how many most recent hourly snapshots are to be kept at any given time. Any older snapshots will be removed. Note: specify one more than you wan to keep, e.g. 25 for one day of hourly snapshots alongside the most current one. CEPHFS_SNAP_DAILY Integer, number of how many most recent daily snapshots are to be kept at any given time. CEPHFS_SNAP_WEEKLY Integer, number of how many most recent weekly snapshots are to be kept at any given time.

CEPHFS_SNAP_YEARLY Integer, number of how many most recent yearly snapshots are to be kept at any given time.
