Borg: How to delete a dir/file in an archive?

[rugk]

How can one delete a part of one (or multiple) archive(s) such as a dir or file?
Obviously you cannot use borg delete for that.

However, also borg mount does not work as – at least in my tests – it seems to mount the repo in read-only mode, i.e. I cannot create files in there e.g.

So how can this be accomplished? (With borg itself, without third-party tools… at least, preferably)

Ah, thanks so this example basically shows it:

borg recreate /mnt/backup --exclude home/icke/Pictures/drunk_photos

However this is only available in v1.1.0, so there is no way with borg <1.1.0?
And secondly, does this redownload the archives? When I do not use rechunking or compression?

And thirdly you may include this question in the FAQ.

When I do not use rechunking or compression, does this redownload the archives?

In this case only metadata is processed, the actual data of the archive is not processed.
