Network Wide Backup & Restore Engineering Rules
The Network Wide Backup & Restore engineering considerations for Release
1.0 are as follows:
•Since Network Wide Backup & Restore application is coresident with INM Broadband Release 5.0, the minimal bandwidth for the WAN communication link is 56 Kbits/sec. The recommended bandwidth is 1.544 Mbits (DS1).
•For an OPC connectivity to the INM and Backup & Restore workstation, the minimal recommended bandwidth for the communication link is
56 Kbits/sec.
Engineering Capacities
Disk Space Requirements
The disk space required to store controller backups is dependent on the following:
•number of controllers
•type of controllers
•number of Network Elements which store data on the controller
•number of backups maintained/controller
Following formula can be used to estimate the amount of disk space required specifically for Network Wide Backup and Restore application.
Disk_space_1 = (# of OPCs) * (5 MByte/OPC) * (# of backups to keep)
Disk_space_2 = (# of NPs) * (1 MByte/NP) * (# of backups to keep)
Disk_space_3 = (# of EC1 MOAs) * (TBD) * (# of backups to keep)
Total_disk_space = Disk_space_1 + Disk_space_2 + Disk_space_3
