One method would be to create a class like mentioned below, then activate
and deactivate via cron with the bpclinfo command
bpclinfo <classname> -modify -active
bpclinfo <classname> -modify -inactive
Another method would be to create a class with everyting you need but no
scheduled windows, then call the class via cron to do a manual backup
whenever you want:
bpsched -class <classname> -IB
Yet another method, since you say the data is there one week and gone the
next is to make it "get gone" by using a UARC job (user archive). Since the
backed-up files are deleted if successfully sent to tape and not deleted if
there's a problem, then it's a very sure method of making sure a copy gets
on tape. We do this with our Oracle archived-redo - we never simply delete
it, we archive it instead.
It's pretty easy to do a "first Saturday of the month" type of backup with
cron since you can do entries like this
0 8 1-7 * 6 /usr/local/backup_job

Subject: [Veritas-bu] RE: What is the BEST WAY to schedule a monthly
backup (without 4. 5)
Hi Geoff,
Although there is no easy way, the way we handled it was the following
(Assuming NBDC 3.2 or 3.4 on Solaris):
Create a class specifically to handle this job. Schedule it for the night
or morning after the data gets placed... let's say it get's placed on the
Friday of the week, have the job run either on a Friday night or Saturday
morning. You don't need to worry about number of days. Just set it on a
normal daily schedule. What you do have to worry about is manually
activating it for the 'weekend' that you have to back it up and deactivating
it before the next weekend.
Those who have Perl scripting done well could probably automate this a lot
better. The could create some script and/or cron job to modify the class.
This would involve modifying the netbackup/db/class/<classname>/info file
entry "ACTIVE" to 0 to make it active and then 1 to deactivate it.
Hope that helps.
Sandy
