Please note that for "repokey" encryption mode (default), the file
containing the key (<repo>/config) is, in your case, on your local disk.

For recovery, you must have the passphrase and the key, so be careful to
have a backup (see borg key ...).

Ah, ok, then you have the config (key) in there.

As long as the filesystems work as they should and you can always
recover data, key and passphrase, this seems ok.

All caches and index files can be rebuilt from repo/data.
It may take a while though, depending on repo size.
