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

.B ::

# 0. Have borg 2.0 installed on client AND server, have a b12 repo copy for testing.
|
|
.sp
|
|
# 1. Create a new "related" repository:
|
|
# here, the existing borg 1.2 repo used repokey\-blake2 (and aes\-ctr mode),
|
|
# thus we use repokey\-blake2\-aes\-ocb for the new borg 2.0 repo.
|
|
# staying with the same chunk id algorithm (blake2) and with the same
|
|
# key material (via \-\-other\-repo <oldrepo>) will make deduplication work
|
|
# between old archives (copied with borg transfer) and future ones.
|
|
# the AEAD cipher does not matter (everything must be re\-encrypted and
|
|
# re\-authenticated anyway), you could also choose repokey\-blake2\-chacha20\-poly1305.
|
|
# in case your old borg repo did not use blake2, just remove the "\-blake2".
