Manual VNX database backup
Use this procedure to back up and save a copy of the VNX database without
waiting for an hourly automatic backup.
Step Action
1. Log in to the network server.
2. List the VNX database backup files by typing:
$ ls –l nasdb*
A display similar to the following appears:
-rw-r--r-- 1 nasadmin nasadmin 1920308 May 4 12:03
nasdb_backup.1.tar.gz
-rw-r--r-- 1 nasadmin root 1022219 Mar 23 19:32
nasdb_backup.b.tar.gz
Ensure that a version of nasdb_backup.1.tar is listed with the current date and time. If a
current version is not present, ensure that nasadmin is the group and owner of
nasdb_backup.1.tar.gz and _nasbkup.
3. To ensure that the VNX database backup does not fill the root file system, check the root
file system free space by typing:
$ df -k /
The system returns the amount of space in the root directory in kilobytes (KB). Ensure
that the free space is more than the size of the most recent VNX database backup.
4. Create a backup file of the VNX database by using this command syntax:
$ /nas/sbin/nasdb_backup /nas /celerra/backup <yymmdd>
where <yymmdd> is the last two digits of the current year, the two-digit month, and the
two-digit day.
The following appears:
NAS_DB backup in progress .....NAS_DB checkpoint in
progress.....done
