Sybase IntelliSnap Backup Copy Operation Overview

The IntelliSnap backup copy operation supports the following interfaces:

  • File System Backup Copy

  • Dump Based Backup Copy

You can choose the interface based on your requirements and resource availability.

Note: The backup copy operation is only supported on the client computers that run the Version 11 Commvault software.

File System Backup Copy

The Commvault software does the following things:

  • Classifies the job type as FULL

  • Mounts the snapshots

  • Clones the snapshot device and creates the volume group and logical volumes to mount the snapshot

  • Queries the index that is created by the snapshot to identify files to back up to a tape library or a magnetic library, and generates a collect file for the backup copy

  • Backs up the files to either a tape library or a magnetic library

  • Unmounts the snapshot

  • Archives the index that is created for the backup copy operations

Dump Based Backup Copy

There are two server options for the dump based backup copy:

  • A previously configured Sybase server

  • A temporary auxiliary Sybase Server

Previously Configured Sybase Server

The following rules apply to the previously configured Sybase server option. The Commvault software:

  • Considers the job type as FULL

  • Mounts the snapshots

  • Clones the snap device and creates the volume group and logical volumes to mount the snapshot

  • Queries the index created by the snap, to identify the manifest file, database files and associated device files

  • Mounts the database on the auxiliary server by using the following command 

    MOUNT DATABASE ALL FROM <MANIFEST-FILE> USING <DEVICE-NAME> AS <DEVICE-PATH>

  • Initiates a traditional dump based backup copy operation by using the ‘DUMP DATABASE’ command

  • Unmounts the databases on the auxiliary server

  • Unmounts the snapshot

Temporary Auxiliary Sybase Server

The following rules apply to the temporary auxiliary Sybase Server option. The Commvault software:

  • Considers the job type as FULL

  • Mounts the snapshots

  • Clones the snap device and creates the volume group and logical volumes to mount the snapshot

  • Queries the index created by the snap, to identify the manifest file, database files and associated device files

  • Mounts the database on the auxiliary server by using the following command 

    MOUNT DATABASE ALL FROM <MANIFEST-FILE> USING <DEVICE-NAME> AS <DEVICE-PATH>

  • Initiates a traditional dump based backup copy operation by using the ‘DUMP DATABASE’ command

  • Unmounts the databases on the auxiliary server

  • Unmounts the snapshot

  • Deletes the temporary Sybase server

Verify the following configuration before you perform a backup copy:

  • The Sybase version must be the same as the source

  • The page size must be the same as the source

  • The character set must be the same as the source

  • The sort order must be the same as the source
