I want to copy (not move) my Timeshift Snapshots (Rsync) from my existing drive to another drive. Both drives are ext4. As far as I searched I am not able to find any viable results.
If not possible, just why?

TLDR
sudo rsync -az -H --delete --numeric-ids /path/to/timeshift path/to/destination/
Where,
-a
: Archive mode (i.e. recurse into directories, and preserve symlinks, file permissions, file modification times, file group, file owner, device files & special files)
-z
: Compress file data during the transfer
H
: Preserve hard links (i.e. copy hard links as hard links)
--delete
: Delete extraneous files from the receiving side (ones that aren’t on the sending side), but only for the directories that are being synchronized i.e. keep exact replica of your /path/to/timeshift
directory.
--numeric-ids
: Transfer numeric group and user IDs rather than using user and group names and mapping them at both ends.
--progress
: Show progress during transfer.
--log-file="/var/log/my-rsync-script.log"
: Log what rsync command is doing to the /var/log/my-rsync-script.log file.

Nice addition of solution.
In time Lemmy will replace reddit for tech questions. Give it a few years!
Thanks man.
replace reddit for tech questions.
The thing is as of right now most Lemmy users are just tech enthusiasts. We want all sort of people to create a more robust community. I want to Lemmy to fully replace reddit in terms of amount of users, communities, posts and activeness.
Let’s just give Lemmy some time.
Surely just copying the files over should do the job? For a single snapshot, that is, otherwise you’ll probably be duplicating a lot of deduplicated space by copying every file out of every backup.
I believe using rsync and telling it to maintain hard links should work.

It gives me an error ‘cannot copy special files’. Even when doing as root.
The article confuses me a bit. But I’ll look into it.
Thank you.
It seems to me like the copy utility you’re using (file manager?) doesn’t maintain soft links/hard links. You may need a command line tool to do the copying that does support it, like rsync, or a different GUI tool (though I admit I don’t know for sure what GUI tools specifically support this).
