We are using a tape environment for our backups. One of the issues i have with commvaults storage policy is that it doesn't really have a difference on how it does full backups. Our retention cycles are a daily backup (Differentials) of 7 days 1 cycle, weekly full 28 days 1 cycle, and a monthly full with 1095 days +.
Currently with how the storage policy is set up it is running to the default, all the data is being dumped to one tape and usually has monthly, daily and weekly data on the same tape. I notice when i pull my monthlies i sometimes will see that the weekly fulls and daily are eating up space that could be used to fill more monthly fulls unto the tape.
I was wondering what would be the best practice to separate the monthly full away from the other backup retentions of the storage policy? Would it be something along th3e lines of creating an aux copy in the storage policy and just copy the last weekly full to the aux copy to separate the monthly full from the other data? or is this something that can be done with the schedules i assign to the storage policy? When I select a schedule, under “Advanced” under the “Backup Task Options”, in the “Media” tab there are two options for Starting “New Media” and “Mark Media full on Sucess”. Would this also be a viable option, or would this create a new tape for each client associated to the schedule for its monthly full?
