Calendar Schedule

Hi all, We want to backup our master server every Sunday directly on tape. The last Sunday of every moth, the tape has to be assigned to a volume pool other than the volume pool of the policy (--...

    Thanks for all your replies! :-) This sounds as if I'll get the desired result with the schedules I had in mind.

    I have now set up two schedules:
    schedule 1: 1st, 2nd, 3rd, 4th Sunday with retention 1 month
    schedule 2: Last Sunday with retention 1 year

    If I understood correctly, schedule 2 should be the one executed on the last Sunday in month since the retention is higher than in schedule 1.

    I'll try to go with this an will see if it works. The idea of switching to the 1st Sunday is good but I would have to change our whole company backup rotation schedule to implement this strategy. But I'll definitely will consider it if the setup above won't work.

Backup frequency determines schedule priority
 
If more than one automatic schedule is due for a client within a policy, the backup frequency determines the schedule that NetBackup uses:
Jobs from the schedule with the lower frequency (longer period between backups) always have higher priority. For example, a schedule with a backup frequency of one year has priority over a schedule with a backup frequency of one month.
 
 If NetBackup encounters a backup policy with two schedules (one full, one incremental) that are each due to run:
 
a.    if each is within the defined time window, and
b.    if each is configured with the same frequency value, the schedule that is first alphabetically runs first.
 
 
For example, NetBackup prioritizes the following three schedules in the following order:
 
1 monthly_full (frequency is one month)
2 weekly_full (frequency is two weeks)
3 daily_incremental (frequency is one week)
If all three schedules are due for a client, NetBackup adds the job for the monthly full to the worklist and skips the other two. How NetBackup prioritizes each backup job that it adds to its worklist is
explained in Chapter 2 of the NetBackup Administrator’s Guide, Volume II.
