Dear list,
since I cannot edit the wiki, I wanted to make sure to share this
supplemental method of
https://sourceforge.net/apps/mediawiki/backuppc/index.php?title=How_to_import_data_for_a_backup
with you.
We were tasked with importing a host with several hundreds of
gigabytes behind a relatively slow link, and so we employed the
station wago method[0]: we shipped a filesystem dump to the remote
location and made it available on a host on the same network segment
as the BackupPC server and ran an rsync to the remote location to
make sure the dump was up-to-date.
0. http://en.wikipedia.org/wiki/Sneakernet#Non-fiction
Then — and this is the nice part — we chrooted into the filesystem,
started sshd on port 22222, and added the following to
~backuppc/.ssh/config on the BackupPC server:
Host the.new.host
Hostname the.temporary.host
HostKeyAlias the.new.host
CheckHostIP no
AddressFamily inet
Port 22222
After the initial backup had completed, just removing the stanza
makes BackupPC interact with the actual host — but it never knew the
difference.
Hope this helps someone,
--
