From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Newbie to BTRFS- how do I use Timeshift to create backups on another SSD? (pawb.social)

Hey there, folks! Currently playing around with a laptop that's got three SSDs. Running Arch but that isn't quite related. I have everything configured on one SSD, the other two are totally fresh. What do I need to do to setup one of those fresh SSDs for Timeshift backups? Please walk me through it from the very start- I think I understand some parts but I'm not too certain.

I can format the drives using mkfs.btrfs without any issues, but I'm confused about how I can add subvolumes and configure their root permissions properly to allow Timeshift snapshots.

EDIT: I see now that I misunderstood what Timeshift does. New question- which tool can I use to make a backup of my entire filesystem onto another drive such that it can be restored?

I have gone from borgbackup to rdiff-backup to reduce complexity and dependencies. rdiff-backup's incremental strategy needs more space than deduplication from borgbackup, but you don't need fuse and borg itself to restore your latest backup.

With rdiff-backup you can just use cp -a to restore all your files. Only if you need a file you deleted ages ago, you need it.

I relied on borgbackup for a long time, never had an incident. But then I wanted to try the new replication borg2 feature and almost lost my original borg1 repo. With rdiff-backup you can just rsync the repo to another drive and have two copies of your offline offsite redundant backup. Encryption is a non-issue, you can run it on top of every other filesystem and LUKS or over SSH.

Granted, I just switched to rdiff-backup, but I am loving the simplicity of it already.
