20.2 Backing up NNMi data
The NNMi backup command (nnmbackup.ovpl) copies key NNMi file system data and some or all of the tables in the NNMi Postgres database to a specified target directory. Each backup operation stores files in a parent directory called nnm-bak-timestamp inside the target directory. You can specify the -noTimeStamp option to save disk space, in which case the parent directory is named simply nnm-bak. When a backup is performed after a previous backup with the -noTimeStamp option in effect, the previous backup is renamed nnm-bak.previous, thereby creating a rolling backup. This renaming occurs after the second backup has been completed to protect against any loss of backup data.
The NNMi backup command can create a tar archive of the backup data. You can use any tool of your choice to compress backup files. You can also use any appropriate tool to save a copy of a backup. For details, see the nnmbackup.ovpl Reference Page.
