redrum Posted February 6 Share Posted February 6 Im new to unraid but starting to get familiar with the OS. Id like to use an old spare PC to setup as a backup device. Question is: would it make any sense to purchase a second unraid license and create this PC as a 2nd server that my main server backs up to? Or is there different software/methods that are more practical for this? Should I just use a raid config in the backup PC and sync the data to the backup server using something like syncthing? I would appreciate some advice from the folks that have experience backing up their servers on the best/easiest way to achieve this. Thanks in advance. Quote Link to comment
T0rqueWr3nch Posted February 6 Share Posted February 6 I don't want to take away business from Unraid and I have never used the Unraid My Servers (which I think is now Unraid Connect?) functionality, so if there are reasons to recommend that route, I hope others will chime in here. In the meantime, I'll give you some keywords to research: How big is the data set that we're talking here? Enough to fit on a single drive? If so, as a beginner, I'd recommend rsync with the Unassigned Devices plugin. Another option, and possibly the best one to use long-term, is borgmatic, but the configuration may be a bit intimidating (especially if you're new), so you don't have to start there.

redrum Posted February 6 Author Share Posted February 6 I have less than 10TB of data to backup. I was thinking of running (2) 10TB HDDs in a raid one at a seperate location. Would rsync work from a 2nd location or would it need to be connected to the main server? Quote Link to comment
T0rqueWr3nch Posted February 6 Share Posted February 6 rsync can work over SSH to the second server (borgmatic can as well). If you're going to buy two hard drives, I'd probably just stick with Unraid for the second server in case you need to expand. The additional cost of a basic Unraid license is marginal and for a good cause! With this kind of redundancy, do you have plans for offsite (3-2-1 principle)? Quote Link to comment
redrum Posted February 6 Author Share Posted February 6 I will have 2 copies of the data (2 servers) and one of those servers will be offsite. Im not sure if thats a 3-2-1 or just a 2-1 but i am comfortable with that amount of redundancy. I will go have a look at rsync and borgmatic now. Thank you for the advice. Quote Link to comment
redrum Posted February 6 Author Share Posted February 6 Rsync looks like what I will be going with. Borgmatic was too intimidating for my skill level as im not a native linux user. That fellow on YT spaceinvader seems to have a video for almost every scenario doesn’t he? Lol Quote Link to comment
redrum Posted February 7 Author Share Posted February 7 Another question... can I use one PC to run OpnSense AND (2) 8TB drives in a raid one that is used as a backup with rsync? Or does OpnSense need to be ran on a standalone PC? Quote Link to comment
