Backup fails due to long runtime - backup hangs

[Jan Macenka]

Are there any insights or resulutions to this? Also am trying (for the 3rd time) to transfer a NextCloud-backup from a Public-Cloud Server to an on-prem instance at a client. Backup Size about 300 GB. The transfer initiates just fine but after a while just seems to get "stuck" at "64M@0MBps" Download speed for hours even though I can test that the connection exists and even run some small load-tests to check that transfer is possible.

Is there some way to restart the import in append mode? After all it tried to import via rsync form a Backup. However if I restart the import it starts over again ignoring all the progress/downloads made before.

And advise here how to get the situation un-stuck?

At this point I'd even be ok with manually rsync-ing the contents of the App to the new system and then just rebuilding the App there from scratch.

There is no resume logic currently. Have you tried to tweak the part-size, concurrency and memory limit for the backup in the advanced backup settings?
