Partial Backup
If you are shadowing, you can change your partial backups to take place on the shadow system. If
you have remote users accessing local data to be stored, your backup procedure will change as well.
Below is the process we recommend for partial backups.
Action Enter Explanation
Flush the pipeline
(optional)
:RUN
NBFLUSH.PUB.NETBASE,STOPWAIT;PARM=s
hadownode
(on the master node)
This step is optional. If
performed, it will force all
updates in the shadowing
pipeline to post to the
shadow files, giving you a
sync point at which time
both the master and
shadow data matches.
This step does not interfere
with production on the
master system.
Stop post
:RUN NBCTRL.PUB.NETBASE;INFO="STOP
POST"
(on the shadow node)
This step is required if post
was not stopped via
NBFLUSH. (This frees the
files to be stored.)
Stop NFA access
:RUN NBCTRL.PUB.NETBASE;INFO="STOP
REMOTE"
(on the shadow node)
This step is required if you
have remote users
accessing data on this
system which you want to
backup.
Perform backup
however you do it (on the shadow node)
Resume posting
:RUN NBCTRL.PUB.NETBASE;INFO="START
POST"
(on the shadow node)
This tells NetBase to catch
up, posting any
transactions that took place
on the master while the
backup was being
performed on the shadow.
Resume NFA
access
:RUN NBCTRL.PUB.NETBASE;INFO="START
REMOTE"
(on the shadow node)
This instructs NetBase to
allow remote users to
access local data.
