Deleting files and directorys from sys volume

[pagy]

Can anybody tell me what files and directorys I can safely delete from my sys volume? The volume is running out of space and I have no spare drive slots in the server for more hard drives. The server acts as the backup server so job logs are constantly being added to sys. I have already deleted the following directorys:
Win95
Winnt
Consoleone
It is a Netware 5 server upto SP6a, there are no archived files form any support packs installs on the server.
The backup software is Backup Exec 9
