Documentation: --copy-links may cause huge backups

[aryoda]

The use of --copy-links should be mentioned in our FAQ as a reason for huge backups (if the backups source folder contains one or multiple links to target folder with large disk space consumption).

Also a clear warning in the GUI could be helpful too (as tooltip or in the checkbox label):

I agree that "Copy links (dereference symbolic links)" is a confusing description. I think "Follow symbolic links" would be much clearer.

We might even consider spelling out the literal rsync options that our settings include. In that case, this checkbox (and other, accordingly) might be labelled: "--copy-links: Follow symbolic links"

I'm also fine with an FAQ entry to warn of including symlinks to large folders with this option.

But I don't think we need to issue an extra warning in the GUI. If people click around in the "Expert options" to activate an option regarding symbolic links, and they have symbolic links to huge folders in their included paths, then I think they can be expected to understand the consequences.

Or am I out of touch? ;)

FAQ is good idea.

...
"--copy-links: Follow symbolic links"

I like that idea.

Brings me again to a big redesign of the settings dialog. ;)
Maybe "Follow symbolic links" is a good start to prevent an exploding PR. 🤣

No. Especially people clicking around in Expert Options do operate on their own risk. ;)

Totally fine for me (nothing to add 😉)
