hi,
there is no restriction on how many jobs you can run simultaneously in arcserve. As a matter of fact any backup solution as long as you have sufficient number of devices.
for example : if you have a tape library with 4 tape drives then you can run only 4 jobs to the tape drive. But if you have created 10 FSDs(backup2disk) and kept them in different groups then you can run a total of 14 jobs.
can you please update how many number of tape drives are available with the client and how many FSDs.
Are the FSDs placed in different groups as if you have 10 FSDs in group labled "b2d" and you are trying to run 10 backups pointed to the same group. Then you will not be able to run simultaneous backups.
As the GROUP is locked when a backup is running if the devices are FSDs or single tape drives.
So you need to organise them in different groups to be able to run multiple jobs at the same time.
post the screen shots of the destination tab when you try to create a new backup job. And also when do you get this error is it when you try to submit a backup job or when the backup job is running.
