We are in the process of implementing NBU 4.5 and are trying to use
Calendar Based Scheduling.  We have discovered that NBU submits multiple=

backups during a given backup window for Netware clients and we believe
it also only affects NT/W2K clients.  Unix clients, we do not know yet. =

For Netware, we have a backup a window at night from 10:00 pm to 6:00 am=

the next morning.  We have discovered that NBU schedules the backups at
10:00 pm but then turns around and schedules the backups again at 12:10
am after the 10:00 pm has only completed.  It does not happen for all
clients but it does happen.  We normally only see it scheduled twice in
a given night though.  Has anyone else come across this issue=3F  Has
anyone talked to Veritas on this yet=3F  And is there a Netbackup fix
coming soon=3F=20

The other issue that comes up then, is that with Calendar Based
Scheduling you are only allowed to run one backup per 24 hour period for=

a client in a given policy.  The 24 hour period is 12:00 am to 12:00 pm.=

So in the situation above,  after the backup is run a second time at
12:00 am, it will not run the next night at 10:00 pm when the backup
window opens up but wait until after 12:00 am when a new 24 hour period
begins.  So we are losing time on our backup window because Calendar
Based Scheduling only allows for 1 backup per 24 hours for a given
client in a given policy.  Has others come across this issue also=3F  Ho=
w
do you get around it=3F  Has anyone approached Veritas on this
restriction. =20

We like the flexibility of Calendar Based Scheduling but this bug on
duplicate backups in a given night and the 24 hour hard window has
caused us some problems as we try to setup our environment. =20


Any feedback or suggestions would be greatly appreciated.  Thanks!
