But if you have a really big repository and that you want to take backups from more than one computer you will have to wait until borg have recreated all those zillions of hashes.  Is there a way to avoid this ?  \r\n\r\nIf I understand well, it's the location where the cache/index is saved that cause problems (fill the root or your home and recalculation delay when accessed from another computer where the cache/index  is not there.  Couldn't the index/cache be saved with the backup at the end and restored from the archive when we need to access the archive ?  It must be loaded from the ~/.cache/borg directory anyway. "}}
