LTO5 - 1 month - pool

Hello, all!

I have a little question about optimization of used space on our MSL Library.

Most of our backups in DP are protected for 1-2 weeks.

But there are some that are protected for 4 weeks. But both of them are written to the same filesystem pool, the same tapes.

Thats why I think these 4 weeks backups prevent tapes from being expired. Will it be better to have a special 4 week/1 month pool for such backups?
