I have a server with a large amount of storage. I also have a bunch of large USB drives that I would like to use as a backup volume.My question is, on Linux, is there any reliable way to do a storage pool with multiple usb drives? If possible, being able to add more on the way.The backup server would be running on Linux, so should I use LVM? ZFS? Anything else?
Recommendation for usb drive pool
linux;lvm;usb drive;zfs;storage
I would suggest to use ZFS, due to the fact, I trust in ZFS to guarantee the data integrity due to it checksums. But it depends on the size of your storage. What is huge for you? 5 TB, 50 TB or several hundred TB? In that case it might be better to use a tape drive than dealing with USB devices. I backup my local server storage to a couple of external USB3 hard drives via ZFS send and receive feature. I am talking about 12 TB data so far. But in case you need more than 5-10 disks I would switch to tape backup.
