Upload backups to S3-compatible cloud storage

[mlazzarotto]

I was wondering if there was a way to copy a backup from PBS and then upload it to cloud storage such as S3 or Backblaze B2.
The utility of this would be to have offsite backups.

I've already tried mounting the B2 bucket via the s3fs program, but apparently PBS and s3fs don't get along.

Therefore, I am currently making backups 2 times: the first time on PBS, and the second time with vzdump from Proxmox on a local disk. At the end of the second backup I use a hook script and rclone to upload the files to B2.
It works, but it's quite a bummer to have to backup 2 times in order to upload it to the cloud.

makes mostly sense with the new PBS 3.3+ push function. Can be configured as remote store either in PBS or directly as PBS alternative in PVE and will act as proxy for S3.

Thank you. It seems exactly what I need.
