Has anyone out there developed a good method of doing backups on the Apollos? We have recently received a MSD6250 tape drive and on all of our other machines we use 'dump.' Unfortunately, there is no dump for the Apollos (SR10?) so we have to use WBAK and RBAK. One of the problems seems to be that RBAK and WBAK don't handle links very well. Any information would be appreciated and if there is sufficient interest I will port my results to the net.

What is wrong with WBAK/RBAK for doing dumps; we use it all the time with the APOLLO 6250 tape drive and it works fine. What is the problem with links to which you refer. I certainly hope APOLLO never supports the 4.2BSD DUMP program. That program requires an idle file system (typically making you to take the system down and run single user) to get a guaranteed good dump of the disk; WBAK has no such problems. In our SUN network, we have to keep a spare eagle around and in the middle of the night we transfer file systems from other machines to the spare. Then we backup the now-idle spare disk. That's incredibly painful compared to just running a backup over the network with WBAK. It's also very nice that you use the same program for system dumps as you would to write a simple tape to send to another site. Leonard
