The only thing I have changed is --backup-room=4000 (3000 before). So there seems to be a relation.

Re: No need to prune the repo with 3 Petabyte :)

The first version of the auto prune feature used MB instead of GB as the size unit. ¿Is there any possibility that you have mixed different versions of the program's constituents?.

Re: No need to prune the repo with 3 Petabyte :)

No I have just the latest version and never installed any other.

But, within the SAME job it is sometimes right and one VM later it is wrong..

I don't understand WHEN a check is triggered at all, because there are 11 VM this job includes, but only 2 checks. Should it check once or after each VM?

Re: No need to prune the repo with 3 Petabyte :)

Now I'm completely lost. This happens after backup up the first VM of a set, and the job stops

I think I'll better start a new repository :S

Re: No need to prune the repo with 3 Petabyte :)

If you pass 3072000 GB (3298534883328000 bytes), you are playing russian roulette with the integer limits supported by the system, as some inner calculations use bytes as the base unit. That does not mean that it won't succeed though.

On the other hand, if your VMs are huge you can also hit the /tmp filesystem limit, as some intermediate data is stored on /tmp

Re: No need to prune the repo with 3 Petabyte :)

If you pass 3 072 000 GB (3 298 534 883 328 000 bytes), you are playing russian roulette with the integer limits supported by the system, as some inner calculations use bytes as the base unit. That does not mean that it won't succeed though.

The log  reads 3089855Mb = ~3Tb.  Emmm, you don't tell me, that I can't use a target/repository with more than 3TB (3145728 MB) ? Do you?

How can I send you a log file (it is a bit to much to post here)?
