Back Up Tables with Copydb Command
Before using this procedure, see the chapter “Loading and Unloading Databases” to understand how copydb works.
To back up tables with copydb
1. Create a temporary working directory for the copy.in and copy.out scripts and move to this directory. For example, you might issue the following commands at the operating system prompt:
Windows:
mkdir D:\tmp\mydir.backup
D:
cd \tmp\mydir.backup
Linux:
mkdir /tmp/mydir.backup
cd /tmp/mydir.backup
2. To back up specified tables, issue the following command at the operating system prompt:
copydb dbname tablename {tablename}
To back up all the tables, views, and procedures that you own in the database, issue the following command at the operating system prompt:
copydb dbname
This creates copy.out and copy.in scripts for the objects copied.
3. To copy the data out of the database, issue the following command from the operating system:
sql dbname <copy.out
This creates a copy of the objects copied from your database.You can store these files on tape or leave them on disk.
To restore data from a copydb backup, you run the copy.in script.
