Recommendations for Restoring an IDS Database 

 

Before restoring IDS logical logs, dbspaces, and blobspaces, you must note the 
following: 

■ 

Restores always consist of the complete backed-up set of data. You cannot 
restore these objects individually unless they are damaged; to restore 
damaged dbspaces and blobspaces, you must perform a disaster recovery 
restore. 

■ 

When performing disaster recovery, you may need to restore critical IDS 
files located in the \etc directory, under the Informix home directory. 

Important! Be cautious with this procedure; restoring critical files 
overwrites the current files. To determine when you should restore the 
critical boot files, see the IBM Informix documentation. 

■ 

If you are executing a full restore, shut down all IDS services before 
starting the restore operation.  

■ 

The Restore by Tree view is the supported format. 

■ 

If you are restoring an Informix instance with the Last Logical Log option 
selected, ensure that you assign a correct value to the restore job and 
save it in the emergency boot file. 

■ 

A restore job will fail if you attempt to restore multiple Informix instances 
on the same media because CA ARCserve Backup cannot restore the 
instances sequentially. To restore multiple Informix instances, restore 
them individually by submitting a new job for each instance, after the 
previous instance has been successfully restored.
