Re: [BackupPC-users] is it possible to shortcut the 1st backup?

[Matthew G. <mg...@gr...>]

Thanks for your reply.  I understand what you're getting at and I tried several ways to do that.  I was able to set things up so the paths are exactly the same on the two machines (the local and the remote client).

But for some reason I cannot get the local backup to actually run.  I tried both rsync and tar transfer methods - both fail.   I thought maybe it was related to permissions but I tested command line versions of rsync while logged in as the backupPC user and those all worked.

Below is the log output.   Not sure why it's not working - again it's the local backup that is not working (the remote one works great).

thanks,
Matt

full backup started for directory /

Xfer PIDs are now 25010
Rsync command pid is 25010
Read EOF: Connection reset by peer
Tried again: got 0 bytes
Done: 0 files, 0 bytes
Got fatal error during xfer (Unable to read 4 bytes)
Backup aborted (Unable to read 4 bytes)
Not saving this as a partial backup since it has fewer files than the prior one (got 0 and 0 files versus 0)

Use the $Conf{ClientNameAlias} = '127.0.0.1'; value to point to the
local machine, and ensure that the paths to the data on the local
machine match the path to the data on the remote machine.

You can use bind mounts (mount -o bind, see the man page for mount) to
make existing path appear somewhere else, etc...

OR, if you really must use a different path for the first backup, after
the backup completes, go into /var/lib/backuppc/pc/<hostname>/0/ and
rename the first directory.
eg, moving from /var/backup/remote to / can be done like this:
mv f%2fvar%2fbackup%2fremote f%2f

Note, every file is prepended with the letter f, and a / is translated
to %2f

Then do another backup and make sure everything is going to the right place.

Adam
