You should be able to either "load" the script from the host file, reference it in the config.pl master file (with some appropriate perl code if you want to retrict its usage to just some hosts) or use my method of creating a general purpose hosts file for Windows that specific Windows hosts can link to... ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/

[BackupPC-users] Adding a max and warning line to the backup pool size?
