remove of data cached by borg

[nbehrnd]

Running borg backup with vorta as GUI in an instance of Linux Debian, I notice each time data are written into ~/.cache/borg of the computer where borg and vorta are installed and started. For me, after removing temporary data (including system cache) with bleachbit and a completely recorded backup from vorta, du -h typically records close to 800MB in ~/.cache/borg. Because these data are in in a folder with name borg, I assume these data belong to borg. So far, I did not observe difficulties to run vorta (and via vorta, borg) to record a new backup, restore a backup/a single file from a backup, compare two backups with each other, etc. after removing these intermediate data.

The vorta GUI offers to run some shell commands after a successful recording of a backup. This possibly can be used to automatically remove directory ~/.cache/borg accessible (including erasing) without elevated (sudo) privileges:

My question: does borg already include an option to remove the temporary data (which eventually could be invoked by vorta, too)?

Vorta's discussion board includes a thread where ~/.cache/borg is mentioned (link), however the specific address to readthedocs.io just above the post's screen photo no longer is successfully resolved. Commands described in the documentation creation and adjacent sections focus on generation and managing already recorded backups, so far I did not spot an entry relevant to my intent.

The observations refer to Linux Debian 12/bookworm with borg 1.2.2 and vorta 0.8.7, both directly installed from the OSes repositories.

The snippet of code the first address provides indeed was helpful, though it was not understood right away. To ease how to trade the affairs in such a situation, especially for those used to use borg indirectly via vorta, I filed a PR (#7049) so that the documentation is even more valuable than it already is. Thank you.

borg doesn't have option to remove the temporary data
