Recreating database

Support
1

I made full backup, total 41 GB. It passed without error (but it takes more than 5 days)
After that i exported configuration file, install Duplicati on another server (both server 2016), imported configuration file and tried to restore a folder with files total size aprox 10 MB.
2 hours passed, Running task: Recreating database … Process stuck nearly 90%

FWIW I’m in the same position and, from reading a bunch of threads here, recreating can take forever especially if there are a lot of backup versions and there’s little to no indication that anything’s actually happening.

However, if you’re on Windows, you can use Windows built-in Resource Monitor and go to the Disk section and you’ll be able to see IO reads and writes to the Duplicati temp directory from the System process which - and if there’s a developer out there please tell me if this is correct - I assume means something’s happening even if it looks like it isn’t.

It,s a good idea, but I stopped restoring.
I will try to do it with synthetic small test.
In general, I start to fear about data in the case of recovery to another computer.
also a big problem is recovery time.
