Basically, with the defaults, it caches the metadata of the files it backed up, into a local borg cache. It doesn't even need to read anything at all from the destination (s3ql) file system so long as the cache is intact. If this cache is lost or corrupt, borg has to read (download, in the case of s3ql) the entire repository to rebuild the cache. -- -:-:- David K.
