Full Operating System Database Backup
A full Operating System backup takes a backup of the database files. The advantage of a full backup is that it is self-contained and simple to understand. Disadvantages to an OS backup are the amount of storage space required to store the backup, the amount of time to take the backup, and the lack of options to restore only a subset of the database.
To back up the database:
1. Stop the applications accessing the database.
2. Shut down the Vector instance.
3. Copy the database files and configuration files to a safe place using tar, cpio, or another utility.
4. Start up the Vector instance.
5. Resume the applications accessing the database.
To restore the database:
1. Stop the applications accessing the database.
2. Shut down the Vector instance.
3. Copy the database file and configuration files from the safe place using tar, cpio, or another utility.
4. Start up the Vector instance.
5. Resume the applications accessing the database.
If the server has completely crashed and cannot be recovered then you may have to reinstall the Vector software before you can restore the database.
