+1I am a little unsure about how synthetic consolidation works.
If you run only a synthetic backup on a given day and no other backups, will that synthetic backup contain data from the same day?
Or does it have to have an incremental backup running just before in order to capture data from the same day?

Hi
Synthetic full will take the last increment that has ben performed and generate a synthfull backup with a timestamp from the day you scheduled this synthfull job.
If the last backup was a full or a synthfull, then it would generate a new restore point from that day, but in reality, the content would be unchanged..
So, if your last incremental backup was performed 5 days ago, then you could be surprised to discover that your Synthfull contains backup data from 5 days earlier..
So, yes, if you want to have a Synthfull that contains data from the day you run it, you have to perform an incremental just before the synthfull.

+13Synthetic full backups consolidate the data from the latest full backup or synthetic full backup together with any subsequent incremental backups, instead of reading and backing up data directly from the client computer. Since synthetic full backups do not back up data from the client computer, this operation imposes no load on the client computer.
During a synthetic full backup, a list of objects from previous backup is generated and the latest version of each object is considered to build new backup image.
