How to set backup to limit the number of full backups to 2 ?
Hi everybody :-)
My new problem :
I would like to set a backup so that there are a maximum of 2 full backups at time.
I was thinking that 1 full backup every 3 differential backups and a maximum of 1 complete chain will be the right setting but, not :
With this setting, :
day 1 : backup_full_b1_s1_v1
day 2 : backup_diff_b1_s2_v1
day 3 : backup_diff_b1_s3_v1
day 4 : backup_diff_b1_s4_v1
day 5 : backup_full_b2_s1_v1 and all previous backups are deleted. So I have not the last 5 day backups.
With a quota of 2 full chain:
day 1 : backup_full_b1_s1_v1
day 2 : backup_diff_b1_s2_v1
day 3 : backup_diff_b1_s3_v1
day 4 : backup_diff_b1_s4_v1
day 5 : backup_full_b2_s1_v1
day 6 : backup_diff_b2_s2_v1
day 3 : backup_diff_b2_s3_v1
day 4 : backup_diff_b2_s4_v1
day 5 : backup_full_b3_s1_v1 and the 4 first backups are deleted.
The problem is that needs to store a 3rd complete backup before the 4 oldiest are deleted.
Do you know this problem ?
What can I do to limit the complete backups to 2 maxi at time ?
Thanks.
Stéphane.

Stéphane, you need to use the option to 'Store no more than 2 recent version chains' for automatic cleanup. This will keep your 2 full backups & associated differential files and only delete the oldest chain after a 3rd new full backup has been created.
Acronis have always taken the approach of not deleting old backup files until after a new backup has been created successfully - this to avoid leaving the user with no valid backup.

Hi Enchantech,
Hi Steve,
Hi Everybody :-)
Sorry I made a mistake, I'm using ATI2019, not 2021. This post is not exactly at the right place.
After reading your answers, I finally undersatnd that having a maximum of 1 complete chain with no more than 2 complete backups at time is not possible.
Either the backup number returns to one each new complete backup if "Store no more than xxx recent version chains" is set to 1,
either Acronis must do 3 complete backups if I alway want to have a least the 4 last days.
It would be possible if the oldiest complete chain was deleted just after the last differential backup of the newest chain.
But Acronis doesn't do that ...
Thanks for your answers.
Stéphane.
