Full Backups

Full backups provide the most comprehensive protection of data.

Backups for any client start with a full backup. If the database is in NOARCHIVELOG mode, you should perform offline backup only.

You can perform a full backup of an online or offline database.

Use the following steps to run a full backup:

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> and click Backup.
  3. Select Full as the backup type and click Immediate.
  4. Click OK.

Data that is backed up for any Oracle instance configured on the Oracle RAC node is lost if the configured Oracle instance is hard-deleted.

Incremental Backups

Incremental backups can be performed when the database is online.

The incremental backups will fail if the database is offline.

An incremental backup contains only data that is new or has changed since the last backup, regardless of the type. On average, incremental backups consume less media and use less resources than full backups. 

The illustration clarifies the nature of full and incremental backups.

Follow steps given below to perform an incremental backup:

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> and click Backup.
  3. Select Incremental as the backup type and click Immediate.
  4. Click OK.

    You can track the progress of the job from the Job Controller.  When the backup job has completed, the Job Controller displays Completed.

Cumulative Incremental Backups

In a cumulative level n backup, all the data changes since the most recent backup at level n-1 or lower are backed up.

For example, in a cumulative level 2 backup, data changes since the most recent level 1 backup are backed up. If no level 1 backup is available, data changes since the base level 0 backup are backed up.

Cumulative incremental backups reduce restore times because you need one incremental backup from any particular level. However, cumulative backups require more space and time because they duplicate the work done by previous backups at the same level.

By default, the incremental level for cumulative backups is 1.

Follow the steps below to perform a cumulative incremental backup:

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> and click Backup.
  3. Select Incremental as the backup type, and then type or select the incremental level in the Oracle Incremental Level box.
  4. Select the Cumulative check box and click Immediate.
  5. Click OK.

    You can track the progress of the job from the Job Controller.  When the backup job has completed, the Job Controller displays Completed.

Archive Log Backups

An archive log backup captures the archive redo logs generated during database transactions.

Archive log backups are useful when you want to recover database transactions that have been lost due to an operating system or disk failure. You can apply these archive logs to an online backup in order to recover a database.

By default full backups include both data and archive logs. However, you can also perform separate archive log backups.

In order to perform a backup of the archive logs:

  • The database has to be in ARCHIVELOG mode.
  • Subclient should have been configured for archive log backups. See Creating A Subclient for Log Backups for step-by-step instructions to create a separate subclient for archive logs.

All Archive Logs

Use the following steps to backup all archive logs. Note that this is the default option:

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> configured for archive log backup, and then click Backup.
  3. Click Advanced.
  4. Click the Backup Archive Logs tab.
  1. Click All.
  2. Click OK.

By Number of Days

Use the following steps to backup archive logs older than a specified number of days.

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> configured for archive log backup, and then click Backup.
  3. Click Advanced.
  4. Click the Backup Archive Logs tab.
  1. Click Older than n Days, and type or select the number of days older than which the archive logs are to be backed up.

    For example, to backup logs older than 10 days, type 10.

  2. Click OK.

Use the following steps to backup archive logs not older than a specified number of days.

  3. Select the Start Time check box and enter the start time after which the logs were generated.
  4. Select the End Time check box and enter the time before which the logs were generated.
  5. Click OK.

By Log Sequence Number

Log Sequence Number uniquely identifies an archive log. For example, if you create a database with two online log files, then the first file is assigned log sequence number 1. When the first file fills Oracle switches to the second file and assigns a log sequence number of 2; when it switches back to the first file, it assigns log sequence number 3, and so forth.

Use the following steps to backup archive logs within a specific range of log sequence numbers:

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> configured for archive log backup, and then click Backup.
  3. Click Advanced.
  4. Click the Backup Archive Logs tab.
  1. Click By Log Seq Num.
  2. Select the Start Seq Num check box and enter the start sequence number of logs to be backed up.
  3. Select the End Seq Num check box and enter the end sequence number of logs to be backed up.
  4. Click OK.

By System Change Number

System Change Number (SCN) is a stamp that defines a committed version of a database at a point in time. Oracle assigns every committed transaction a unique SCN. For example, SCNs of two successive transactions committed could be 576601 and 576799.

Use the following steps to backup archive logs within a specific range of system change numbers:

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> configured for archive log backup, and then click Backup.
  3. Click Advanced.

  1. Click OK.

Control File Backups

The control file contains metadata about the physical structure of the database including the location of all files, the current database state etc. Each control file is associated with only one database. The control file backups are used for creating standby databases from the CommCell Console. Standby databases are used during database recovery.

The subclients need to be configured prior to running control file backups; see Enable/ Disable Control File Backups for a Specific Subclient for step-by-step instructions.

Use the following steps to backup the control file:

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> configured for control file backup, and click Backup.
  3. Click Advanced.
  4. Click the Oracle Options tab.
  5. Select the Backup Controlfile for Standby check box.
  6. Click OK.

Container and Pluggable Database Backups

Oracle 12c supports container and pluggable databases. SnapProtect supports the backup of container and pluggable databases.You can backup the entire container database or one or more pluggable databases.

Container databases can be backed up by creating an instance for the container database. Single and multiple pluggable databases can be separately backed up through custom RMAN scripts.

Backing Up a Container Database

When you backup a container database, all pluggable databases that are part of the container database are also backed up.

  1. Add an instance for the container database.
  2. Follow the steps to create a full or incremental backup, where the instance is the one added for the container database.

Backing Up a Single Pluggable Database

  1. Create and customize an RMAN script file on the client computer, where the last line in the script specifies the pluggable database to back up. The line has the following format, with "pluggable_database_name" specifying the pluggable database to back up.

    pluggable database pluggable_database_name;

    Example: RMAN script backing up the pluggable database "SINGLE_PDB".

    run {
        setlimit channel ch1 maxopenfiles 8;

        backup
        incremental level = 0
        filesperset = 32
        pluggable database SINGLE_PDB
      ;
    }
    exit;

  2. Execute the RMAN script. See Running RMAN Scripts from Third Party Command Line.

Backing Up Multiple Pluggable Databases

  1. Create and customize an RMAN script file on the client computer, where the last line in the script specifies the pluggable databases to back up. The line has the following format, with "pluggable_database_name1" through "pluggable_databaseN. Each database must be separated by a ",".

    pluggable database pluggable_database_name1, ..pluggable_database_nameN;

    Example: RMAN script backing up the pluggable databases "PLUG_DB1" and "PLUG_DB2".

    run {
        setlimit channel ch1 maxopenfiles 8;
        backup
         incremental level = 0
         filesperset = 32
         pluggable database PLUG_DB1, PLUG_DB2
        ;
    }
    exit;

  2. Execute the RMAN script. See Running RMAN Scripts from Third Party Command Line.

Previewing RMAN Scripts from CommCell Console

Prior to running a backup operation from the CommCell Console, you can preview the corresponding RMAN script for the backup job. This is useful to determine whether the selected backup options will yield the desired result in the script. You can also manually copy and save the generated RMAN script to your computer and later execute the script from the command line.

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> and click Backup.
  3. Click Script Preview.
  4. Click OK.

Customizing RMAN Scripts from CommCell Console

In addition to previewing the RMAN script, you can also modify the script from the CommCell Console. This is useful when you want to include the RMAN commands that are not supported by the software.

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> configured for archive log backup, and then click Backup.
  3. Click Advanced.
  1. Click the Custom rman script tab.
  2. Select the Customize script check box.
  3. Edit the RMAN script as required, and then click OK.

Cataloging RMAN Backup Pieces

When the Oracle recovery catalog does not know about the backup pieces you want to restore, you can run this procedure to add the backup pieces from the tape or media to the Oracle recovery catalog.

  1. On the RMAN command line, create and run an RMAN script similar to the one below.

    For information on the supported SBT parameters, see SBT Parameters.

    configure channel device type 'sbt_tape' PARMS="SBT_LIBRARY=software_install_path/Base/libobk.so,ENV=(CVOraRacDBName=<DBName>)”;

    The SBT_LIBRARY path for the various platforms are listed below:

    • AIX with 64 bit Oracle - <Client Agent Install Path>/Base64/libobk.a(shr.o)
    • Solaris with 64 bit Oracle -<Client Agent Install Path>/Base64/libobk.so
    • Linux on System Z with 64 bit Oracle - <Client Agent Install Path>/Base64/libobk.so
    • All Other UNIX platforms -<Client Agent Install Path>/Base/libobk.so
  2. On the RMAN command line, type the following command to verify the configuration.

    RMAN>show all;

  3. On the RMAN command line, type the following command to catalog the backup pieces.

    catalog device ‘sbt_tape’ backuppiece ‘backuppiecename1’,‘backuppiecename2’;

Performing Parallel Backups with Multiple DataPaths for Load Sharing

Sometimes, the resources on a single datapath may not be enough to perform a backup job. When you configure a primary storage policy copy with multiple datapaths and perform a backup, this backup job can get the reservations from multiple datapaths that are present in the primary copy. This will share the load of your backups between multiple DataPaths.

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> and click Backup.
  3. Select backup type and click Immediate to run the job immediately.
  4. Click OK.
  5. You can track the progress of the job from the Job Controller window of the CommCell console.
  6. Right-click the client computer, click View and then click View Job History.
    1. Example:

      In the following image, when you right-click the Job ID 32747 and select View Media, you can view that the resources are allocated on all the 4 drives that were part of different datapaths while Configuring Multiple Data Paths for Load Sharing. This example displays that the resource allocation is performed on to different media datapaths with effective load sharing.

    Example of JM Log with RM Messages enabled:

Enhancing Backup Performance

Backup performance can be increased by setting the RMAN Disk Ratio value for distributing the backup load across disks. By default, the RMAN disk ratio is not set.

For example, consider data files distributed across 10 disks that supply data at 10 bytes/second and a tape drive that needs 40 bytes/second to keep streaming. In this case, you can set the disk ratio value to 4, which will direct RMAN to include data files from 4 disks in each backup set.

Backup performance can also be enhanced by setting additional configurations at the subclient level. See Enhancing Backup Performance for more details.

Use the following steps to set the RMAN disk ratio:
  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient> and click Backup.
  3. Click Advanced.
  4. Click the Oracle Options tab.
  5. Select the Enable Rman Disk Ratio check box.
  6. Type the number of disks in the Rman Disk Ratio box.
  7. Click OK.

Validating Backups for Restore

You can validate previously run backups to ensure the integrity of the data for successful restores.

Use the following steps to validate the backup jobs of a subclient:

  1. From the CommCell Browser, navigate to Client Computers | <RAC Client> | <Instance>.
  2. Right-click the <Subclient>, and then click Properties.
  3. Click the Backup Arguments tab, and then click the Options tab.
  4. Select the Validate check box.
  5. Click OK.

Managing Jobs
