I've been doing backups for years, but in the past the companies I've worked for have had a tape rotation policy in place. Now I'm tasked with creating one for my current company which has none....

Basicly I need to know how many tapes I will need for a specific amount of data, with a given "off site" rotaion. Specificly I have three "media stores" (daily, weekly, monthy), How many tapes will I need if I send the dailies off site for 1 week, the weeklies off for 3months, and monthlies off for a year.

Idealy, I would like to have an Excell template that would allow me to do "what-ifs" (there is some talk about "splitting" the backups into several different rotaions). Or a program that will warn an operator what tapes/containers to call back from off-site.

Thanks

Larry

Thanks. I guess, I should have given more details.

I already have a backup software solution. I use Backup exec, and have two libraries, one with one drive the other with two. I currently backup 25 servers and go though around 12 tapes a week (10 lto2, and 2 lto3). Currently we do not send any tapes off site and the "tape rotaion" is "find the oldest tape and move it to Scratch Media". I need to "fix" this proccess but to do so I need add alot of more tapes. My boss will not accept a purchase order for "alot" and wants me to justify any purchase of the number of tapes I need, weather it's one or a hundred.

Thanks again.
