Backup Recommendations
There are many ways to make a backup of the hard disk. The method used is for
you to decide. The important point to remember is DO IT. If no specific method
has been decided upon, use the MS-DOS Backup command. Refer to the
MS-DOS user’s guide for additional information.
The following actions are strongly recommended when performing the backup
procedure.
The backup procedure must be performed on a directory basis. Do not
attempt to back up single files.
This is especially important for the PCNMS\DCWRK directory since this
directory can contain various transaction log files. If the NMS is shut
down properly, the data in these log files is automatically incorporated
into the database. However, if the NMS shuts down too quickly (as in the
case of a power failure, for example), any existing log files remain intact
and must be included in the backup and restore procedure. Otherwise,
the database is corrupted.
When backing up the PCNMS\DCWRK directory, the NMS must not be
running. If it is, you take the risk of losing statistical information (i.e., call
statistics). Therefore, you may not have a current picture of your network
when you are through with the backup procedure.
Database Functions
The following database functions are provided with NMS:
Database Export – enables you to export information from the database to a
disk file.
Database Import – enables you to import information from a data file into the
database.
Database Reorganization – enables you to reduce fragmentation and
condense the database.
