Sizing backup file

[petitbleu]

Hi,
Is there a sizer for the backup in file mode? Or should you use the classic sizer? And if it is the classic, are there any recommendations on the parameters?

Hello,
if you have the amount of source data, reduction rate, change rate and retention, any calculator / spreadsheet can do it. I know that there are sizing tools on external blogs, but the ones I saw were over-complicated and sometimes even wrong.

NAS backup is incremental forever. There is no (synthetic) full. Technically you can use https://rps.dewin.me/ in forever incremental mode. I just take Excel since NAS backup exists, because the formula is easy.

Code: Select all

source size -> data reduction -> full on disk
changed data size per day -> data reduction -> increment on disk -> multiply with the retention

Best regards,
Hannes
