Correct, the backup process was terminated due to "Child exited
prematurely" every time backuppc attempted to do the backup. You should
look at the host Log file for details of what happened during each
backup attempt. Possibly none of the backups even started due to some
error, possibly each backup ran for some period of time and transferred
some data before failing. We don't know from the limited information you
have provided.

Perhaps you should try the following:
1) login to the backuppc server
2) su - backuppc (or whatever your backuppc user is)
3) /path/to/backuppc/bin/BackupPC_dump -v -f server1 (or whatever the
name of your server is)

This will show you exactly what is happening when backuppc attempts to
do a backup.

You should probably tell the backuppc web interface to not run any
backups for this host for a couple of hours before you do the above, as
I've noticed (at least on the older 2.1 version) that backuppc will
launch a new backup while the command line backup is running, and they
will "step on each others toes" as far as both writing to the same
filenames etc...

Adam
