Hi,

I came in a situation, where customer have only single drive and no disk/file pool available in the environment. Also drive is a manual drive not robot controlled(Library)

They have lto 5 drive and backup is schedule weekly full and daily incremental. I have a query how the data will expire in considering the following scenario. Reuse delay set as one days. They used different cartridge for full backup.

Considering tape size is 1500 GB and retention period is 3 days. They are using new cartridge on Sunday.


Monday incremental : 300GB
Tuesday incremental: 300GB
Wednesday incremental : 300GB
Thursday incremental : 300GB
Friday incremental : 300GB
Saturday needs new cartridge as the data filled upto 1500GB.
On Thursday 300GB portion will be marked as reclaimable space as the retention period is over.
Friday 300GB
Saturday 300GB
and so on....

So how this cartridge will be re-utilized for next backup or what will be the procedure to use the same?
