Delete garbage collection before cutoff

[naseem]

Hey,

does anybody know to start the gc (because using access time cutoff is 1d 5m) early?
I would like to be able to delete manually, regardless of the scheduler.

With kind regards

Naseem

Hi,
you can use the gc-atime-cutoff in the datastore tuning options to configure a cutoff lower than the default. Please make sure to leave gc-atime-safety-check enabled! See https://pbs.proxmox.com/docs/storage.html#tuning

PBS GUI -> Datastore -> nameofthestore -> Prune & GC Jobs -> Garbage Collect Jobs -> Run now

Hey Chris,
i dont understand the manual.
I want to delete a file that I just cut (prune) out.
proxmox-backup-manager datastore update BLABLA --tuning 'sync WTF'.???

TF is a line interface command.
If you don't like CLI, tuning can also be done in the GUI after double-clicking "Tuning Options".

PBS doesn't work like this and this is not possible:
The backed up data is split in a lot of small files ( chunks ), which are referenced by each backup snapshot they are part of. So if one chunk is in backup a of vm 101 and backup b of vm 202 and remove backup the chunk is still there. The garbage collection looks for chunks which are not part of of a snap fshotor the cutoff time ( default 24h 5 m) and removes them only if there is no snapshot including it anymore. This saves a lot of storage space but at the cost that you keed regular housekeeping ( garbage gollection, prune and verify jobs). They are quite fast on fast local storage ( ssds) and quite slow on hdds or network storage ( like nfs shares).
