Are there special techniques or settings to back up a LUKS encrypted drive with Duplicati?
Ubuntu 20.04 with LUKS encrypted SSD at OS installation
After successfully using Duplicati with unencrypted drive for some years, I have installed a new SSD and reinstalled Ubuntu 20.04 with LUKS full disk encryption.
Now when I use Duplicati to backup to either a local NAS or to Backblaze B2, Ubuntu crashes during the backup. A single file backup runs ok, and restoration of that file works, but a larger backup results in OS crash. Some files and folders have been backed up, but not all. On one occasion screen briefly showed error message “Connection to server lost, attempting again in new…”, when connected to the NAS.
Any tips or suggestions?
