How to recover from interrupted backup

Hello
No I’m not deleting DB

Today I tried Duplicati.CommandLine.RecoveryTool.exe
I successfully decrypted files, indexed files and started restore from latest versions - no error message so far. So backup files are probably fine?

EDIT: whole backup (all of 87GB ) was successfully restored via RecoveryTool - so backup files seems really fine.

So maybe main problem is some bug in repair with handling "Unexpected update count: ?
