Find the files occupying most space in a backup archive?

[fdcastel]

How could I find the files occupying most space in a backup archive?

I have a LXC with around ~37GB of data (or so it seems). In my PVE host:

# du -sh /rpool/data/subvol-215-disk-0
37G     /rpool/data/subvol-215-disk-0

However my backups for this LXC are around ~60GB (!?), according to web UI.
BTW: how to get this size via command line?

I tried to mount the archive

proxmox-backup-client mount ct/215/2024-08-18T09:46:51Z root.pxar /mnt/tmp/

But du is not being very helpful:

/mnt/tmp# du -sh *
0       bin
0       boot
0       dev
0       etc
...

I presume the difference in size is probably due to sparse files. Problem is: I have A LOT of them in this container.

I'm looking for a way to find the largest ones, hoping I can exclude some of them from backup.

Login to your container and "find / -type f -size +9G -ls" eg. search for files bigger than 9GB and then go down with less size.

The webUI will show the provisioned size of the drive(s) of the VM/LXC. It does not show the size used by that specific backup. In fact, that's a very tricky piece of information to get when backing up to PBS, as the chunks are shared (deduplicated) among all the backups in the same datastore, whether they are from the same VM/LXC or others.
