Hey thanks a lot for the response Johan! It's taken me a while to figure out
how this is supposed to work and I'm getting closer but still not there.
The file refers to 'tar dumps' but it's unclear to me what that means. Does it
assume that my local backups are in a tar.gz format? They are not. They're
uncompressed and simply live in a folder named after the hostname.
So I created a tar.gz of one of my folders and tried to work on that but
BackupPC_dump doesn't seem to find it:
Running: zcat /home/backup/my_sql_server/my_sql_server_copy
full backup started for directory /samba_shares/
started full dump, share=/samba_shares/
Xfer PIDs are now 6134,6133
xferPids 6134,6133
cmdExecOrEval: about to exec zcat /home/backup/my_sql_server/my_sql_server_copy
gzip: /home/backup/my_sql_server/my_sql_server_copy is a directory -- ignored
Tar exited with error 512 () status
What is the expected value of TarClientCmd? Is it the name of the .gz file? Or
a folder which contains the .gz file(s)
Same question for FILEAREA.
If I were to run BackupPC_dump directly what values can I pass to it?
It appears the script is looking for a .tar.gz file named after the hostname.
Is that accurate? Am I able to import one folder/mount at a time or is it an
all-or-nothing deal?
If I'm guessing correctly would the following import local files into the
BackupPC pool for the server named "my_web_server"?
# - Set TarClientCmd to 'zcat /tmp/bpctar/my_web_server.tar.gz' (as set in
FILEAREA below)
...
TARGETS="my_sql_server" # Manual target list
...
# Your environment
FILEAREA=/tmp/bpctar/my_web_server.tar.gz
### unused for seed ### NEWBPC=/mnt/backuppc # Where new backuppc dir is
mounted, if moving
### unused for seed ### OLDBPC=/srv/backuppc # Where current backuppc dir is
mounted, if moving
### unused for seed ### BPCLNK=/var/lib/backuppc # Where config.pl to in the
config, if moving
BPCBIN=/usr/share/BackupPC/bin # Where BackupPC_* scripts are located
BPCUSR=backuppc # User that runs BackupPC
Thanks again for your help!

Migrate local data into BackupPC pool for remote client
Hi,
Version 4 supports matching files from the pool.
If you are using version 3, the path has to be the same, so you would
have to process the tar file to match the host to be backed up. This
works fine, I used a similar method here:

You may be able to use tar with --strip-components to work around tar
extra paths on the fly.
Good luck!

BackupPC is installed and working great for new hosts. Is there a way to take
the hundreds of GB from old hosts that exist on the backup server and import
them into the BackupPC storage pool?
The old backup system uses rsync to dump all files to a local disk on the same
server where BackupPC is installed, albeit with incorrect file ownership. I
don't want to re-transfer that data over our narrow bandwidth connection if I
don't have to. I believe rsync will sort out permissions and timestamps on its
own.
So far I've created a host in BackupPC and changed the transfer type to 'tar'
and successfully imported one of its mount points, but now the tar sharename is
called "/home/backup/<servername>/cur/<share>/", where the actual share on the
host is simply called /<share>.
My intention is to flip the Xfer method from 'tar' to 'rsync' after I get most
of the larger shares imported via local tar. Is it necessary to associate the
imported files with a specific host or does hard-linking take care of all that?
Thanks!
