I actually solve my backup problem with a windows vm + macrium reflect... a user script turn on the vm everyday at 8:30am, and macrium it's scheduled to run at 9am and shutdown windows when it have finished... the backup in a network share seems faster with macrium... I don't know why, but with rsync after a couple of days it was still running, while for a full backup macrium takes around 4 hours... I has not been able to setup Duplicacy storage... but I didn't spent a lot of time on it... I see lot talks good about Borg, but I didn't tried... I'll do because I would prefer a docker to a vm, so during Christmas holidays I'll make some test with borg! I'm very sad about the recovery problem of duplicati, because I really like its interface! it results very easy, but reading online problems seems its not doing the main things safe (recovery)! Thanx a lot for your suggestions, I'll give a try
