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.

rsync command for mirroring drives (lemmy.ml)

I wanted a sanity check on my current rsync flags. Posts on Reddit seem to highlight the use of rsync -avz for most use cases, for some instances even for when someone asks for mirroring a drive: https://www.reddit.com/r/DataHoarder/comments/rau071/rsync_command_to_mirror_drive/. This has not worked for me for the following case:

Drive #1:

file1.txt
file2.txt

Drive #2:

file1.txt
file2.txt
file3.txt

With -avz, file3 on the destination would not be deleted. With experimenting, I ended up now using rsync -havziP --delete-after --info=progress2 dir1/ dir2/, which actually ended up mirroring the drives for me. My question is: is this the best rsync approach for mirroring drives or was there a better option that works better?

Side note: it is interesting that rclone sync from rclone (https://rclone.org/commands/rclone_sync/) claims to delete by default, while with rsync it seems to be something you have to distinctly mention.

Graphic interface, you just click options. And it has drop downs for favourite folders you've configured before so you can switch between backup/sync locations.

Once you apply it it shows you the CLI command as visual reference
