Grandfather, Father, Son Cleanup option

Thread needs solution

I need to figure out our cleanup strategy for our Exchange backup.

Presently we do a full backup every night at 10PM, then incremental backup every hour from 7AM to 9PM.

If I choose a "Granfather, Father, Son" cleanup scheme what would be saved and for how long?

Hello Joseph,

Thank you for posting your question, I will be happy to help.

With the Grandfather-Father-Son (GFS) backup scheme you are not allowed to back up more often than once a day. The scheme enables you to mark out the daily, weekly and monthly cycles in your daily backup schedule and set the retention periods for the daily, monthly and weekly backups. Since your backup strategy requires more than one backup operations per day, the Grandfather-Father-Son (GFS) backup scheme is unacceptable for you.

I can suggest you to combine two retention rules: Delete backups older than and Keep the archive size within that will allow you to limit both the backups’ lifetime and the archive size.

Maintain the balance between the storage device capacity, the restrictive parameters you set and the cleanup frequency. The retention rules logic assumes that the storage device capacity is much more than the average backup size and the maximum archive size does not come close to the physical storage capacity, but leaves a reasonable reserve.

Due to this, exceeding the archive size that may occur between the cleanup task runs will not be critical for the business process. The rarer the cleanup runs, the more space you need to store backups that outlive their lifetime.
