Question on Backups

[samuk]

I have configured the backups with 7 roll Backup..

From this i gather that on on the 8th day the 1st roll back is over written..and this carries on...

What happens to the full backup over the days?

Day1 - Full Backup
Day 2 -


Day 9 -

Assuming only 5 Roll backs have occured since the full backup - If i was to delete all the roll back, is the full backup file only for Day 1? or is this current for the Day 5?


Thanks in advance for the clarificaiton...

Here's good explanation:

your backup file will represent :
current day : full backup (vbk)
day minus 1 to day minus 6 : incremental files (vbr), needed to restore older backup.

If you were to delete smaller vbr files, you'll lose your roll back files ( backup history), but not affect your last backup intergrity. This the "reverse incremental" veeam backup' feature.
