Backup Copy job space estimation

[luix73]

Hi all
I want to keep, using backup copy job, on a target repository only three LAST DAYS retention point.

I kindly ask you help to understand the space needed on the target repository.
The scenario is:
- VM 100 GB disk
- Disk Usage 80%--------> 80 GB
- Disk change Rate: 15% of the size----------> 15 GB

How many space I need on the copy job target repository if:
1) I use 15 days retention point policy on the local site
2) I use 30 days retention point policy on the local site
3) I use 30 days retention point + 1 monthly retention 12 months + 1 yearly retention 5 years policy on the local site

Remember on the target repository my requirement it is to keep only 3 last days backup
Thanks

Hello Luigi.

Please take a look at Restore Point Simulator made by Timothy Dewin. It allows you to estimate the required disk space based on your retention and job type. Hope it helps, thank you.
