# 0. Have borg 2.0 installed on client AND server, have a b12 repo copy for testing.
|
|
|
|
# 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".
|
|
$ borg --repo ssh://borg2@borgbackup/./tests/b20 rcreate \
|
|
--other-repo ssh://borg2@borgbackup/./tests/b12 -e repokey-blake2-aes-ocb
|
|
|
|
# 2. Check what and how much it would transfer:
|
|
$ borg --repo ssh://borg2@borgbackup/./tests/b20 transfer --upgrader=From12To20 \
|
|
--other-repo ssh://borg2@borgbackup/./tests/b12 --dry-run
|
|
|
|
# 3. Transfer (copy) archives from old repo into new repo (takes time and space!):
|
|
$ borg --repo ssh://borg2@borgbackup/./tests/b20 transfer --upgrader=From12To20 \
|
|
--other-repo ssh://borg2@borgbackup/./tests/b12
|
|
|
|
# 4. Check if we have everything (same as 2.):
|
|
$ borg --repo ssh://borg2@borgbackup/./tests/b20 transfer --upgrader=From12To20 \
|
|
--other-repo ssh://borg2@borgbackup/./tests/b12 --dry-run
