all of that said, you need to get the BackupPC_serverMesg command right, as
indicated here, which you did not in your original post. The syntax for
requesting a backup is
BackupPC_serverMesg backup <hostIP> <host> <user> <backupType>
where <host> *needs to* match a host you defined in BackupPC (i.e. if you
named your host "foo", you can't use "foo.domain.com", "cname-for-foo", or
"1.2.3.4" here) and <hostIP> should probably be identical to <host> unless
you know what you are doing (hint: you don't; using an IP or something else
that resolves to the same IP might occasionally work, but a quick glance at
the code suggests that this may break BackupPC internal synchronisation).
<user> is informational only, if I remember correctly, and backupType is one
of "auto", -1, "doIncr", 0, "doFull", 1 with the text corresponding to the
following number.
If you want to request three backups, then that's three individual
BackupPC_serverMesg commands.
Hope that helps.

Holger
