Rocky Linux and Disk Imaging

Is there an equivalent to Acronis Products, O & O BackUp, etc. for Linux? Spoiler alert! Not anymore (there was way back in the Acronis 9.5 days, O & O never supported Linux).

OK, how about Clonezilla or Rescuezilla? They're great, but one is required to boot from an ISO Image. So not so great for those nightly automated backups like Acronis, O & O, and many other do in Windows (thank you VSS (Volume Shadow Copy Service))

Let's keep looking. FSArchiver! Yup, it supports "SnapShots" (equivalent to VSS in Windows) via ruBackUp

How about Bacula or BareOS? Sure, but it's complicated. So back to something simple, so back to FSArchiver. Well, sort of. What about "live" backups? IE, no need to reboot to a Clonezilla ISO or CD. Clone a live / running OS, sort of like how Acronis and other software for Windows has been doing it for more than a decade using the VSS (Volume Shadow Copy) Service, AKA "Snap Shots".

OK, RUBackUp then. Cool.

• Restore a BackUp
  • If a duplicate partition (Volume if LMV) is mounted;
    • umount /mnt/sdb3
    • lvremove WhatEverVolumeGroupName/VolumeName (look in /dev for the Volume Group, then look in that Directory for the Volume Name): lvremove VG_01_Clone/root
      • To Reverse "unmounting an LVM device";
        • vgcfgrestore VG_01_Clone -f /etc/lvm/archive/WhatEverVolumeGroup.vg (--test switch can be added to see if it will work)
        • lvscan (it will probably show the restored item as 'inactive')
        • lvchange -a y /dev/VG_01_Clone/root
        • mount -av (to mount everything or remount everything in fstab)
        • from: https://www.thegeekdiary.com/how-to-recover-deleted-logical-volume-lv-in-lvm-using-vgcfgrestore/
      • OR
        • lvcreate -n root --size 200G VG_01_Clone
        • ...hmm, still working on this
        • Good info here: https://tuxfixer.com/how-to-create-lvm-volume-group-and-logical-volume/
  • If not, create a partition (LVM, etc) ideally equal in size to the original (it can be as small as the expanded size of the backup)
