we have a customer with a specific ruleset for backups. It boils down to this:
-daily backups of the most important VMs (Monday through Sunday)
-weekly backup of less important VMs (usually Saturday)
-active full backups on Saturday of ALL VMs
-last full backup chain goes to tape - each day (after the daily jobs are done)
Each VM has its own backup job.
The daily tape job has to finish before work hours the next day. To achieve this, I had to set the daily jobs to start after each other to reduce the whole backup window.
So instead of this:
-mailserver1 - 6pm
-mailserver2 - 7pm
-dc1 - 8pm
-dc2 - 9pm
...I chained the backup jobs like this:
-mailserver1 - 6pm
-mailserver2 - after mailserver1
-dc1 - after mailserver2
-dc2 - after dc1
This reduces the backup time considerably so that the tape job has more than enough time to do its job.
Saturday is Full Backup Day, so every backup job has the Active Full Backup flag set to Saturday.
Here's the problem:
An Active Full makes a job finish considerably later, which means that for example mailserver1 starts at 6pm on Saturday and finishes around ~8pm (instead of ~6.15pm), mailserver2 now starts at ~8pm and finishes around 10pm, dc1 starts around 10pm and finishes around midnight - and dc2 now starts on Sunday and won't actually do an Active Full because its AF flag is set for Saturday. It'll do an incremental and will completely leave out a restore point for Saturday.
My question now is: Is there any way to tell a backup job to start an Active Full on a different time than its usual schedule? I'd prefer to start the Active Full for Saturday at around 9am, which gives all jobs plenty of time to finish their AF on Saturday.
Or is there an alternative that I've overlooked? Like, creating a dedicated AF backup job for all VMs on Saturday at 9am and leaving the daily jobs as they are? But then how would the daily incrementals "know" about the full backup on Saturday?
Timing out the jobs that would start on Sunday and then setting Sunday as AF day for these jobs seems a bit finicky to me, since I might end up with two full backups for these jobs for Sunday...
Thanks for your ideas in advance!
