About SCCM site backup

Question

The SCCM server gets a site backup every day.
Backup is for one generation only.
I want to change the destination of this backup.
So, as for the capacity to check the capacity, is the capacity of the backup destination temporarily required for the capacity of two backups when acquiring the backup of the site?
Or is it okay if there is enough space for one backup?

I want to see if the backup mechanism deletes the current backup after a new backup is taken or overwrites the current backup.

Answer 1

Hi @QX0232176 ,

Based on my experience, it is required to prepare two backups when acquiring the backup of the site.

The function of two backups is to avoid the current sccm backup fails, and then we could use the older version.

So the backup mechanism deletes the current backup after a new backup is taken.

Assuming you are referring to the built-in site maintenance task, you can do one of two things:

1. Customize the afterbackup.bat file that COnfigMgr calls at the end of the maintenance task to perform supplemental actions like moving the backup itself so it is not overwritten.
2. Stop using the maintenance task and use a native SQL backup method. (This is my strongly preferred and recommend method btw).

All of this is covered in the official docs at https://learn.microsoft.com/en-us/mem/configmgr/core/servers/manage/backup-and-recovery.
