I am reviewing my course material from vmce course I did last year.
I did not get around to sitting exam and I have a lot of catching up to do.
I have been going through questions from course practice exam and I am trying to verify some answers.
One of the questions is as follows
A Scale out backup repo with one local extent has been configured as follows:
Capacity Tier:
Extend scale out backup repo with object storage Amazon S3 - ENABLED
Copy backups to object storage as soon as they are created - ENABLED
Move Backups to object storage as the age out of operational restore window - ENABLED
Move Backup files older than 31 days
The Question:
12 VMware VMs are being backed up daily by a forward incremental backup job, which has a 14 day retention, creating synthetic full on Saturdays. After running for more than 31 days, which would be accurate?
The Answers:
A. The performance tier will contain all restore points. The capacity tier will contain zero restor points
B. Both the performance tier will contain 14 to 20 days of restore points
C.The performance tier will contain most recent 14 to 20 days of restore points. Capacity tier will contain 31 to 37 days
D.The performance tier will contain most recent 14 to 20 days of restore points. Capacity tier will contain 17 to 23 days
My thought is answer B
Now where probably my confusion sets in is that both co-pilot and chatgpt are adamant that the answer is D.
But According to chatgpt
Best Answer:Performance tier will contain the most recent 14 to 20 days of restore points, capacity tier will contain the older 17 to 23 days of restore points
Why this is correct:• Veeam’s 14-day retention means you’ll always keep 14 most recent daily backups (plus fulls).
• Because synthetic fulls are done weekly (on Saturdays), each backup chain might span 6–7 days (full + incrementals), so depending on the calendar, you might have 14–20 days worth of restore points on the performance tier.
• Everything older than 31 days gets moved to Capacity Tier only, so S3 will hold only those older restore points — typically 17 to 23 days' worth depending on backup chain length.
Maybe I just do not understand the concept but would this move policy not be redundant?
I fail to see how the backups could at all reach 31 days if the retention period is 14 days? I can understand 14-20
