Or a synthetic cumulative, a cumulative or any combination that makes
sense, cumulatives obviating the need for any earlier cumulatives or
differentials.  It's all in the Veritas NetBackup System Administrator's
Guide | Policies | More about synthetic backups.  And RTFM is what the
original poster could have done rather than complain that NetBackup
doesn't work like TSM.

Or whenever; there is no need for immediacy other than the synthetic
full (or synthetic cumulative) is only as current as the latest
incremental it uses.  That's obvious, but I need to remind myself
periocially that I can schedule the synthetic when resources are
available rather than right after the last incremental component.

No, that's what TIR is for.  You can't configure a synthetic without
TIR+move in the policy.

Any reason for that other than just getting used to trusting the
computer with one more new task?  Accurately determining synthetic
content is something a human can do with pencil, paper and time; there
is no magic or guesswork.
