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.

I'm trying to find a good method of making periodic, incremental backups. I assume that the most minimal approach would be to have a Cronjob run rsync periodically, but I'm curious what other solutions may exist.

I'm interested in both command-line, and GUI solutions.

I use rsync+btrfs snapshot solution.

  1. Use rsync to incrementally collect all data into a btrfs subvolume
  2. Deduplicate using duperemove
  3. Create a read-only snapshot of the subvolume

I don't have a backup server, just an external drive that I only connect during backup.

Deduplication is mediocre, I am still looking for snapshot aware duperemove replacement.

I'm not trying to start a flame war, but I'm genuinely curious. Why do people like btrfs over zfs? Btrfs seems very much so "not ready for prime time".

I've only ever run ZFS on a proxmox/server system but doesn't it have a not insignificant amount of resources required to run it? BTRFS is not flawless, but it does have a pretty good feature set.
