Best Way to Figure Out Which VM/LXC Backup Is Using the Most Space?

[SInisterPisces]

Hello,

I've got a @tuxis PBS account and really like it, but I'm still on the free plan for now, so I'm trying to be mindful of my 150 GB total space allotment.

I noticed a spike in usage over the last week or so, and I can't really think of what I've done that might have caused that. 30 GB in 4 days is … surprising. Is there a way in PBS itself to look at the growth rate of the backups for individual VMs or LXC containers?

Trying to figure out what's going on made me realize that I don't really know how to track individual LXC and VM usage of the datastore.



Aside: Compare that to the same data being backed up on my local PBS, which is about 20.9 GB in a week. The biggest difference locally is that I'm keeping more snapshots since I have much more space to work with. (In fact, the local backup has more VMs stored in it since it's an older installation and has more aggressively paranoid snapshot settings.)



Also, it's a really good idea to turn off the Total graph when one of your PBS instances has drastically more space than the other. Look how much easier it is to compare the local PBS to the Tuxis instance once I've got a similar y-axis on both of them.

I rewrote parts of the script (some standard library functions were shadowed, e.g. all) and added more features to it. For example, I added the option to pass vmids as comma separated values as well as ranges and I added functions to summarize and order the list by highest consumption.

@RolandK : The scripts already do check, if chunks are used several times within a given vmid and only count individual referenced chunks. I think checking, if a specific chunk is only used by one...
