I suggest that Sage add the backup feature within the program for HRMS. This feature was in Abra Suite.
I found this in the Sage knowledgebase. It tells you how to back up in the server.
Sage Knowledge base ID 21192 Backup and restore in Sage HRMS".
You might want to contact your partner company and they might write a little script that would make it easy for you to back up right from the client.
