samarrs Posted November 20, 2022 Share Posted November 20, 2022 I have 25 TB of a media share folder I want to cold back up to external drive. For that I bought 2 16TB drives. I was thinking about mounting those as unassigned devices and copy the folder, then disconnect the external drives and store it safe. 1. What is the best way to do this ( Since I have 2 disks and I have no idea how to make pool of 2 unassigned disks) 2. How to make sure next time I plug in, it syncs any modified data? 3. Any tool that I can use similar to rsync. Quote Link to comment
Solution JorgeB Posted November 21, 2022 Solution Share Posted November 21, 2022 You can make a btrfs pool with both devices by adding them to an Unraid pool and then UD will mount it, you can also have and automatic rsync script run on mount. Quote Link to comment
samarrs Posted November 21, 2022 Author Share Posted November 21, 2022 Got it. One question "unraid pool" is it making a pool same as cache pools? Quote Link to comment
JorgeB Posted November 21, 2022 Share Posted November 21, 2022 Yes, you can create multiple pools, add a new pool, assign both devices, format the pool, looks like you'll need the total capacity of both disks so balance the pool to raid0, then you can unassign both devices from the pool, delete it, and keep using the pool with UD, for that you just mount one of the devices and the other one will mount together. 1 Quote Link to comment

samarrs Posted November 21, 2022 Author Share Posted November 21, 2022 (edited) I got the UD pool created. What would be my mount point to set destination for my backup? Edited November 21, 2022 by samarrs Quote Link to comment
JorgeB Posted November 21, 2022 Share Posted November 21, 2022 You can change the mount point name in UD by clicking on it: Then the mount point is going to be /mnt/disks/mountpoint_name Quote Link to comment
samarrs Posted November 21, 2022 Author Share Posted November 21, 2022 It worked out perfectly. I got the rsync script running. 1 Quote Link to comment
