Volume Shadow Copy Service with NTBackup

October 28, 2008

Hi Community,

Looking for a dumb down explanation of VSS with NTBackup by adding /SNAP:on

switch.

We use an application called Syspro, which if we were not a cheap

organization can use a SQL server - however we are stuck with the ISAM data

files for now.

Currently we backup the data nightly, after hours using CA ArcServ tape

backup.

I want to implement a backup that works on weekends to Hard disk and a daily

backup to hard disk.

Now, since the data files are constantly changing through out the day it

makes it difficult to backup the data until off-hours. Does VSS with

ntbackup take a snapshot of the data (all the data) at one specific instance

than use that copy to backup?

Or does it just handle Open files in sequential order... thus not really

getting a accurate copy since other records in tables can change while one

file is being backed up?

If it uses the above, is there a solution to do a real-time synchronization

of the data to another folder - than stop that synchronizing application - do

the backup of that and than restart the resynch?
