About this task

Explains how to backup Network Performance Insight backup contents.

Note: Resiliency might be better achieved with a combination of a periodic backup and a multi-node setup, for example, backup on a multi-node cluster environment.

Procedure

Log in as root or netcool user.
Change to the /<basecamp_Home>/basecamp-storage directory:
For example,
```
# cd /opt/IBM/basecamp/basecamp-storage
```
<basecamp_Home> is the location where the basecamp packages are installed.
Run the following command to display the usage for backup command.
```
# ./bin/backup -help
```
Run the following command to start the Network Performance Insight backup procedure.
```
# ./bin/backup
```
The backup script runs the following tasks in the background:
- Creates and stores Network Performance Insight backup contents in the following HDFS file system directories:
  - Network Performance Insight storage data at /npi/work/storage/.snapshot/<BACKUP_VERSION>/*
    For example:
    /npi/work/storage/.snapshot/npi-1.3.0.0-<timestamp>/*
  - Domain objects at /npi/work/dmbackup/<BACKUP_VERSION>/*.json
    For example:
    /npi/work/dmbackup/npi-1.3.0.0-<timestamp>/snapshot.npi.cfg.domain_names-mgr.json
  Note: <BACKUP_VERSION> is the backup directory with the following naming format: npi-1.3.0.0-yyyyMMddHHmmss
Note: Only the latest backup version is retained in the HDFS file system. All the older backup versions are deleted.
Verify the /<basecamp_Home>/basecamp-storage/logs/basecamp-storage.log file for any issues during the backup procedure.

All messages during backup procedure are logged in basecamp-storage.log file.
