Dry run mode

[Gurumanger]

I am sat wondering how much space I will need for my PBS backup storage.

What would be really good is a dry-run mode where you could run the backup and it will go through all of the reading of the vms and lxcs but just report back what the size of the resulting storage would be when it is done for real.

Maybe that exists or maybe it is too hard to implement but it would be amazing if it were to exist.

Yes, that's an interesting and possibly frustration avoiding idea.

how many vm and lxc ?
you need the same space as your used storage.
imo, dedup + compression will allow keeping more history.

Yes - and what did all that add up to? Be good not to have to guess.

sum up used space of each datastore.

regardless of the actual topic of this thread, this

is slightly incorrect, almost all staff members here are *actual developers*

nonetheless, adding feature requests/bug reports in the bugzilla is a good idea, since it makes it much easier for us to track/assign/etc. them
