[Veritas-bu] How to properly calculate the Catalog

Hello All,

I am trying to use the formula for calculating the catalog and not sure about the results. Has anyone
Calculated the catalog using the formula in the Performance Tuning guide?
Can you please explain how to properly do this?

1 – "When the formula states total backups" ... is this for one Full backup of all data for one day?

Schedule

Incremental - daily - retention 5 weeks
Weekend Full - retention 6 weeks (only first 3 weekends)
Month-End - retention 1 year (last Saturday of the month)

Below is my attempt to calculate this. Any clarification would be appreciated.

-----------------

614GB data back up   * 3 Full Backups (1842GB) * 2 months retention (3684GB) = 3.5 TB
Full

447GB data back up   * 1 Full Monthly Backup (447GB) * 12 months retention (5364GB) = 5.2 TB
Month End Full

122GB
incremental * 30 incr backups monthly (3660GB) * 5 week retention (1.25 months) 4605GB = 3.5 TB
--------------

3.5 TB incr
3.5 TB Weekly Full
5.2 TB Month-End Full

= 12.2 TB = Netbackup catalog size (2%) = 240GB Catalog space

This does not seem right???

Thanks
Jack
