Enhancement: Add command for copying snapshots between repositories

We've added a copy command, allowing you to copy snapshots from one
repository to another.

Note that this process will have to read (download) and write (upload) the
entire snapshot(s) due to the different encryption keys used on the source
and destination repository. Also, the transferred files are not re-chunked,
which may break deduplication between files already stored in the
destination repo and files copied there using this command.

Add copy functionality Add a copy command to copy snapshots between repositories. It allows the user to specify a destination repository, password, password-file, password-command or key-hint to supply the necessary details to open the destination repository. You need to supply a list of snapshots to copy, snapshots which already exist in the destination repository will be skipped. Note, when using the network this becomes rather slow, as it needs to read the blocks, decrypt them using the source key, then encrypt them again using the destination key before finally writing them out to the destination repository. 2019-08-13 16:27:20 +00:00			`Enhancement: Add command for copying snapshots between repositories`
