I'm trying to get an understanding of how GFS retention manages the actual files. I'm hoping a better understanding will allow me to more accurately size our solution.
Given this scenario:
- If I backup all VMs daily and keep 14 restore points. (I see 1 vbk and 13 vib files)
- If I setup a backup copy job to run daily and keep 7 restore points, 4 weekly backups, and 12 monthly backups...
- Does the backup copy job create backup chains or independent backup files?
- If they are chains, is each type of backup considered its own backup chain?
- For example, do the 7 daily backups consist of 1 full backup file (vbk) and 6 incremental backup files (vib)?
- If they're not backup chains, then they must be completely independent full backup files. Is that correct?
- For example, the 7 daily backups consist of 7 full backup files (vbk)?
