I'm looking for some advice on my backup plan. On unraid I have a standard array and a zfs pool with one disk of redundancy. None of the disk in the standard array are formatted to zfs. I run a number of nextcloud-aio in docker, a number of other docker containers and a home assistant vm. I am using the docker compose plugin to manage most of my containers (the nextcloud-aio manages some itself. I have a share on the zfs pool for nextcloud's data and another for general appdata. I also have a share on the array called backup. This backup array has folders for different things that get backed up. Nextcloud-aio backs itself up to folder here using borgbackup. The home assistant vm also manages it own backups to here. I want to setup a way for the appdata to also get backed up here, preferably without having to stop the containers. Here is what I have planned that I would like some feedback on. I plan to make a script that will daily take a snapshot. It will then clone the snapshot. After that it will use some sort of incremental backup software (like borgbackup or duplicati) on the clone to back it up to the array. When the backup is complete I can destroy the clone and start the process again the next day (I would probably leave the clone until the next day and destroy it first thing). I will probably keep a weeks worth of snapshots on the zfs pool but don't want them to be my main backup. Does this seem reasonable? Am I over complicating something? Any preferences between tool like borgbackup and duplicati? From the research I have done on bogbackup and zfs, if nothing in the appdata changes the clone will be identical. This seems to me to indicate that borgbackup won't have trouble deduplicating when it makes its backup of the appdata clone. Is this right? I know this isn't a full backup yet. I still need to come up with a strategy to replicate the backup share off the array. For right now I will probably copy it to a portable drive I have periodically. I do plan to make an offsite unraid server somewhere (a relatives house) at some point. Thanks for any feedback.

I recently moved my unraid system to a new bigger case. The only other part that changed is the power supply. I needed longer cables so I pulled an old one out. It does have a lower rating of 400w. I think the one I was using had 650w. Since that change randomly my system will stop responding. I won't be able to access any of the dockers, VMs, gui or files. I go to the computer and it is still on. If I reset it everything comes back. I have looked in the syslog and nothing at all stands out around the crash. I think it is the power supply though I am surprised 400w isn't enough. Before I get a new one I wanted to see if there was anything else I should check. I've attached the syslog and diagnostics. There are multiple crashes in this syslog but there is one right before the bottom between 18:35 and 19:48 on the 8th. Thanks for any insight. syslog-10.24.1.10.log.txt tower-diagnostics-20230908-2003.zip
