Hi! Since updating to Duplicati 2.2, I cannot complete backups anymore, I’m getting an out of memory error.
I tried to delete & repair the database, but that didn’t help. Then I exported the config, deleted the backup and the remote files, then reimported the backup config, but it still fails. Here’s the log of the fresh first backup I tried:

It ran almost all the way through and failed at the very end. It did create 13 GB worth of remote data. But it still says “Last successful backup: N/A”.
Any help is appreciated!
