I'm considering reversing this setup and saving say 7 restore points to my small NAS and use a copy job to save 30 restore points to the big NAS
That is a good solution. It allows you to keep a short chain of the most recent backups, and keep a longer chain on a separate storage.
there is no option to keep different generations aka weekly/monthly backups in a backup job or maybe I haven't found it?
You can shchedule periodic Full backups
. Is that what you want?
I was now asked to also add a quarterly backup or copy job to backup 1 full backup quarterly to an external HD
Quaterly backups can be done via GFS policy
, however it's only available in Backup Copy Job and cannot be used with rotated drives.
What is the best way to create a quarterly backup to HD?
Considering the limitations I think you should do the following:
1. Keep 7 restore points created by your primary Backup Job on your small NAS
2. Point Backup Copy Job to the big NAS and set it to keep 30 restore points + GFS policy to put monthly and quaterly Fulls aside on the same NAS.
3. Schedule a script that will copy new standalone Fulls that have been produced by GFS policy to the HD
