In the "Define Retention Rules" section of a backup plan, there is a check box for "Create a Synthetic Full if possible" box. I have that check marked. When does the merging magic happen?
What does "if possible" mean? IOW, when would it not be possible to merge incrementals?
For the external X drive, I have "Incrementals" set at "keep 30 backups." Will the merging of incrementals happen on or about the 30th incremental backup? So far in drive X, I see the full backup (00) and sequential backups from 01 through 13. It looks like it hasn't begun to merge incrementals yet. Is this normal?
For the external drive Z, the "Incrementals" is set to "keep 10 backups." Looking at the Z drive, I see a full backup (00) modified on April 22. The next in that series is an incremental with the number 12, then an increment numbered 13. Both 12 and 13 have April 22 as the date modified. Is this normal? Has the merging already happened on that backup set and is that why increment numbers 01 thru 11 are missing? Full backups are supposed to run every Sunday. Why was the full backup modified today (Wednesday April 22)?
In the "Define Retention Rules" section, I'm not real clear what the two options mean:Apply retention rules to matching backup sets in the target folder. Apply retention rules to all backup sets in the target folder.
I read this page several times but still do not know what it means: http://knowledgebase.macrium.com/display/KNOW/_Retention+Rules
For the X drive, "Apply retention rules to matching backup sets in the target folder" is selected.
For the Z drive, "Apply retention rules to all backup sets in the target folder" is selected.
Hoping for more clarification on what these things mean and if it looks like my backups are running correctly. Thanks.
