        --first N                                consider first N archives after other filters were applied
        --last N                                 consider last N archives after other filters were applied
        --oldest TIMESPAN                        consider archives between the oldest archive's timestamp and (oldest + TIMESPAN), e.g. 7d or 12m.
        --newest TIMESPAN                        consider archives between the newest archive's timestamp and (newest - TIMESPAN), e.g. 7d or 12m.
        --older TIMESPAN                         consider archives older than (now - TIMESPAN), e.g. 7d oder 12m.
        --newer TIMESPAN                         consider archives newer than (now - TIMESPAN), e.g. 7d or 12m.


Description
~~~~~~~~~~~

This command transfers archives from one repository to another repository.
Optionally, it can also upgrade the transferred data.
Optionally, it can also recompress the transferred data.

It is easiest (and fastest) to give ``--compression=COMPRESSION --recompress=never`` using
the same COMPRESSION mode as in the SRC_REPO - borg will use that COMPRESSION for metadata (in
any case) and keep data compressed "as is" (saves time as no data compression is needed).

If you want to globally change compression while transferring archives to the DST_REPO,
give ``--compress=WANTED_COMPRESSION --recompress=always``.

Suggested use for general purpose archive transfer (not repo upgrades)::

    # create a related DST_REPO (reusing key material from SRC_REPO), so that
    # chunking and chunk id generation will work in the same way as before.
    borg --repo=DST_REPO rcreate --other-repo=SRC_REPO --encryption=DST_ENC

    # transfer archives from SRC_REPO to DST_REPO
    borg --repo=DST_REPO transfer --other-repo=SRC_REPO --dry-run  # check what it would do
    borg --repo=DST_REPO transfer --other-repo=SRC_REPO            # do it!
    borg --repo=DST_REPO transfer --other-repo=SRC_REPO --dry-run  # check! anything left?

The default is to transfer all archives, including checkpoint archives.

You could use the misc. archive filter options to limit which archives it will
transfer, e.g. using the ``-a`` option. This is recommended for big
repositories with multiple data sets to keep the runtime per invocation lower.

For repository upgrades (e.g. from a borg 1.2 repo to a related borg 2.0 repo), usage is
quite similar to the above::

    # fast: compress metadata with zstd,3, but keep data chunks compressed as they are:
    borg --repo=DST_REPO transfer --other-repo=SRC_REPO --upgrader=From12To20 \
         --compress=zstd,3 --recompress=never

    # compress metadata and recompress data with zstd,3
    borg --repo=DST_REPO transfer --other-repo=SRC_REPO --upgrader=From12To20 \
         --compress=zstd,3 --recompress=always
