round 2. tape recycling


Recommended Posts

Hello,

I thought I had my backups configured correctly.

But I have run out of tape.

First let me define what I ultimatly want.

I have a number of servers that I back up regularily.

I have a 16 tape AIT4 tape library.

I would like a full backup every week.

then incrementals every night.

then when the tapes are full,

allow over wright over the oldest backup

as long as it is older then 1 month.

 

does this make since? too much to ask for?

 

EMC support helped me with my configuration before.

They had me create 4 backup sets.

week1

week2

week3

week4

 

In each backup script

I backup everynight and then do a recycle on a 4 week schedule.

 

I don't love this as it suggests that I only keep backups for a month even if I have miles of free tape.

So I am surprised to find myself out of tape.

A full backup is currently ~400gig.

 

So I should have plenty of room for a month's worth of backups.

 

Can someone help me with my configuration?

 

Thankyou,
