It'd probably be better to do backups by copying files rather than blocks. There are a variety of things that look at filesystems by UUID, and the plus of using them in /etc/fstab is that there are cases where drive order is not deterministic or can change if there's a hardware change (e.g. what is /dev/sda this boot could be /dev/sdc next boot). The UEFI boot manager and GRUB also use UUIDs to find things, so having duplicates is unpredictable. It doesn't apply in this case (just noting it), but you should definitely never do block backups of LVM like this, because LVM will stop when it finds multiple devices with the same UUID. Also, you are putting more wear on the SSD backup drive this way, because you are writing all blocks (whether they're in use or not and whether they've changed or not). If you make new filesystems on your backup drive, mount them somewhere, and then use something like rsync to make your copies, you'll greatly reduce the writes to your SSD and extend its life. -- Chris Adams <li...@cmadams.net> -- _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
