Query on Acronis backup

You essentially have 2 backup sets called b1 & b2. You can keep as many backups as you want as long as you have the space. That is your choice.


However, for practical reasons you may have to limit how many backups you do before you start deleting old ones. If you start running out of space you can delete old backup sets manually. However, you can configure Acronis to do that automatically. There are two options to consider:

• Create a full version after I incremental versions. In the example, I = 4
• Delete version chains older that D days, In the example D = 60

In the example below

• One backup set consists of 1 full backup file + 4 incremental files. After that a new backup set is started.
• If there is not enough space left on the drive to do a backup, backups sets older than 60 days are automatically deleted

How many backup sets your drive will hold depends upon the size of the backup drive divided by the size of each backup set. For example, if each backup set is about 200GB then in theory a 2TB will hold about 10 of them. However, for practical reasons you should limit that to maybe 2-5 backup sets. That way you shouldn't have to worry about running out of space.

For me the biggest problem is figuring out how to configure this so the automatic deletion works without problem. I have to work on tweeking these settings because sometimes I am still forces to delete old backups manually.
