I have a ton of data that I am backing up monthly. However, I am running into an issue where my full backup runs into the next work week. The issue it is causing is my main system ends up fighting for disk IO against the backup job. Is there a way to pause the job, then resume it during a lesser busy time?
A little background. I am backing up 8TB. I have a LTO 3 Tape library that holds 16 tapes. The files I am backing up are highly compressed so backup exec isn't doing any compression. I am getting from about 1.5GB a min to 2GB a min job rate.
I tried the similar method to pausing backup to disk, by pausing the drive, but it continues to plug on. It may pause after it completes that tape, but it just started a new one so I have not seen if that will work yet or not.

As I understand it once the job has started it won't stop until it is finished.  If it runs out of media it will stop processing until it has media to continue.  But you would have to figure out how to intentionally run it out of media at the proper time.

In a situation like this you really have a couple of choices, add additional resources (tape drives or backup to disk device) or add faster devices to decrease the backup window.

Ideally you could add a second tape drive to the library (or someother device to backup to).  That would allow you to split the job into two pieces and you would finish before the next work week.  

If the additional drive isn't a possibility, can you split the job into two pieces?  Get the 1st half of the monthly on week 1 and get the second half on week 2.

hope that helps
Cheers

In all my research that is the same conclusion I came to. Was more or less hoping that someone might have found some way to accomplish this. Thanks for your help.
