NetWitness 11.x backup and restore procedure or script
That's a backup script for 10.6.3 and 10.6.4. It says:
"This backup script has been qualified on the following versions of Security Analytics:
10.6.3.x and 10.6.4.x
Use of this script on any other versions of the product may not give expected results and may not be supported by RSA Customer"
I can confirm this information too.
I was given the same answer in support:
You can't use the backup script for NW11.1 , starting from NW11.2 there is a backup tool that can be used for backup and restore.
