# zfs-keep-and-clean
|
||||
|
||||
## Script sts23.sh
|
||||
### Aufruf:
|
||||
Aufruf: ./sts23.sh <test|echt> <Poolfilter> <Anz. Behalte> [Snapshotfilter]
|
||||
|
||||
|
||||
## Script snpgrpdl.sh (neu)
|
||||
Snapshots nach Datasets und Muster im Snapshotnamen filtern und ggf. löschen.
|
||||
Es können alle bis auf die letzten x Snapshots behalten werden (-k keep).
|
||||
Zu löschende Snapshots werden mit einem '-' gekennzeichnet.
|
||||
|
||||
### Aufruf:
|
||||
```
|
||||
root@zfsrasp~# ./snpgrpdl.sh -h
|
||||
|
||||
Aufruf: snpgrpdl.sh [-htf] [-k keep] <Datasetfilter> [Snapshotfilter]
|
||||
|
||||
-h Hilfe Anzeigen
|
||||
-t Testmodus. Simulation von löschen ohne Nachfragen (benötigt -k)
|
||||
-f Echtmodus. Snapshots löschen ohne Nachfragen (benötigt -k)
|
||||
-k <Anzahl> Anzahl der letzten Snapshots die behalten werden sollen.
|
||||
Rest wird gelöscht. Ohne -t oder -f kommt Abfrage ob gelöscht werden soll.
|
||||
```
|
||||
### Beispiele:
|
||||
Nur Filtern (ohne löschen):
|
||||
```
|
||||
