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.

What You'll Need

  • Of Course: https://rubackup.gitlab.io/ (This is just a simple Copy / Paste of files to "install")
    • After installing (probably to /opt/rubackup, just to keep things inline with their examples);
      • ln -s rubackup.rb rubackup (enables one to simply type rubackup instead of rubackup.rb)
      • export PATH="/opt/rubackup:$PATH" (makes the "rubackup command" available from any directory)
  • And for LVM Support, which is needed for "Live" BackUps (and snapshots): https://www.fsarchiver.org/ (for the latest version, this requires make, make config, make install, and all the associated compiling tools)

Quick Tips

  • RUBACKUP is configured to look in /etc/rubackup.d for "BackUp Scripts"
  • Also see this for addtional configuration items: Installing FSArchiver on Rocky Linux
  • ZSTD is busted in Rocky Linux 9 (and probably others) as of some time in 2023
  • https://rubackup.gitlab.io/
  • Directory for BackUp Configuration Files Default Location: /etc/rubackup.d
  • rubackup --config '/etc/rubackup.d/Rocky8_ROOT-Partition_to-FSArchive.yaml' --loglevel 6 --logfile /var/log/Rocky_ALL-Partition.log

  • Restore a BackUp
    • If a duplicate partition (Volume if LMV) is mounted;
    • 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)
