ZFS Prune Snapshots
|
||
|
===================
|
||
|
|
||
|
Remove snapshots from one or more zpools that match given criteria
|
||
|
|
||
|
Examples
|
||
|
--------
|
||
|
|
||
|
Remove snapshots older than a week across all zpools
|
||
|
|
||
|
zfs-prune-snapshots 1w
|
||
|
|
||
|
Same as above, but with increased verbosity and without
|
||
|
actually deleting any snapshots (dry-run)
|
||
|
|
||
|
zfs-prune-snapshots -vn 1w
|
||
|
|
||
|
Remove snapshots older than 3 weeks on tank1 and tank2/backup.
|
||
|
Note that this script will recurse through *all* of tank1 and
|
||
|
*all* datasets below tank2/backup
|
||
|
|
||
|
zfs-prune-snapshots 3w tank1 tank2/backup
|
||
|
|
||
|
Remove snapshots older than a month on the zones pool that start
|
||
|
with the string "autosnap_"
|
||
|
|
||
|
zfs-prune-snapshots 1M -p 'autosnap_' zones
|
||
|
|
||
|
Timespec
|
||
|
--------
|
||
|
|
||
|
The first argument denotes how old a snapshot must be for it to
|
||
|
be considered for deletion - possible specifiers are
|
||
|
|
||
|
- `s` seconds
|
||
|
- `m` minutes
|
||
|
- `h` hours
|
||
|
- `d` days
|
||
|
- `w` weeks
|
||
|
- `M` months
|
||
|
- `y` years
|
||
|
|
||
