Hello,
I have a PBS 1.0-11 with 1.5 tb of space. I am backupping three VMs with disks 800 800 and 500. Disks are almost empty if I do backups with zstd I get vma.gz of 390, 270, 59 gb. Now I use PBS and I fill 1.5gtb without backupping the third VM. It seems compression is not applied but I have specified in the backup job.
What can I do?
Thanks,
Mario
 
how do you determine that it fills that much?
empty blocks really do not take up space

what does df -h say?
can you post the task logs of the backups?
 
I suppose this log wiil reply to all your questions:

When I choose PBS as a destination I see the compression is grayed out and is fixed at zstd. But in this case it seems it is not compressing.
 
no this has nothing to do with compression... can you show us the content listing of the datastore?
and a task log of a recent garbage collect ?
 
I have just deleted again the datastore because when it fills the entire machine goes down because the filesystem is full.
This evening I will do again. But please note that I am starting from scratch: this was the FIRST backup of my three VMs. So there is no log of a garbage collect: I have created the backup server just two days ago.
 
I have found some garbage collect logs:

can you post the versions from the client and server side?
 
This is the backup log in proxmox server:

So what's happened? It is a PBS just installed I do not understand because this one does not want to work correctly.
 
please post the info i requested, else i cannot help you
df -h
content listing
versions of server and client
also a task log from a regular vzdump (non pbs) would be helpful to see the resulting sizes

I cannot give you easily a df -h because I have to start a backup cycle. Then the disk is full and so gui and all services will stop. Anyway I will try.

I have already extracted them from vzdump in the first post: vma.gz of 390, 270, 59 gb (this are gzip compressed, not zstd)

This is df -h before backups:
