How do I configure my Backup Strategy using Backup Exec 11D
In my current environment I'm using a Sony LIB-162 which contains an 8 slot AIT Library. I'd like to implement a GrandFather-Father-Son backup strategy. M-Thur I'd like to do Incrementals and on Fridays full backups. I have a total of 20 tapes. I'd like to only have to change out the tapes once a week or every two weeks if possible. If someone could get me going in the right direction as far as how to configure the device pools, and media sets that would be great.

Yes I'll be backing up close to 500gb.
errr I forgot to ask what is the native capacity for each tape?

No problem. The capacity is 200gb. Also I just found out that the total amount of data that I will have to back up is around 3.TB. Also the tape drive I have is a Sony AIT Lib-81(8slots) not 162 as initially stated. We do have a AIT Lib-162 (16slots) but it's been sent back to sony for repair. So all I have now is the Lib-81 & a 2TB snap server to use for backups.
sorry for long wait here. I seem to have more questions every time you provide more answers :P
So that 3 TB total is how much you need to back up for each Full backup? If so that doesn't give you much room with 20 Tapes @ 4TB total native capacity...or is that 3TB a total amount for say... a months worth of weekly full and daily incremental backups?
Then comes the question--How how far back are you required to go with the tapes? If you only need one month's worth of backups then you might be able to squeeze by.
As for cutting down your tape swapping time... that will be very hard to do with an 8 slot library. With that said, mind if I share a bit about my set up and compare?

This really got me going in the right direction.
This varies very heavily on the amount of data being backed up. Have you already calculated how many GB of data total will be backed up?
