Hi Team,

 Is there a handy sheet to forecast media requirement for a month. I am aware that media size, retention and frequency of backups are the governing factors in determing the no of medias required. Please let me know in case anybody has similar sheet to forecast medias.

Thanks
Sid

Unfortunately no, as you have already pointed out there are too many parameters involved however I will use “Tape written” report (This report shows tape consumption in the past) to help me with forecasting.

I vault to iron mountain every day, so I can guestimate my needs pretty easily, based on history.

Having said that, my Oracle team updated their retentions, and went to a once a week full with daily incremental backups, and my weekly data usage went down 100 TB.

Tape count? Not so much...

2017 average - 278 tapes a week, 700TB.

2018 YTD - 273 tapes a week, 578TB... 

so much for saving tapes...
