Advanced Backup - FlexFrame for IntelliSnap Oracle

Table of Contents

Full Backups

You can run full backups for IntelliSnap and File System/RMAN backup copy operations.

A full backup is the most comprehensive backup and is the baseline for incremental backups.

  1. From the CommCell Browser, expand Client Computers > client > Oracle > instance.
  2. Right-click the subclient and click Backup.
  3. On the Backup Options for Subclient dialog box, select the backup type and job initiation:
    1. In the Backup Type section, select Full.
    2. In the Job Initiation section, specify whether to run the backup now or if it will be scheduled.

      Note: If you selected Schedule, set up the schedule.

      For information on configuring a backup schedule, see Schedule Backups.

  4. Click OK to close the Backup Options dialog box.

You can run full backups for IntelliSnap and File System/RMAN backup copy operations.

Incremental Backups

You can perform an incremental backup when the Oracle database is online or offline.

For more information on incremental backups, see Incremental Backups.

  1. From the CommCell Browser, expand Client Computers > client > Oracle > instance.
  2. Right-click the subclient and click Backup.
  3. On the Backup Options for Subclient dialog box, select the backup type and job initiation:
    1. In the Backup Type section, select Incremental.
    2. In the Job Initiation section, specify whether to run the backup now or if it will be scheduled.

      Note: If you selected Schedule, set up the schedule.

      For information on configuring a backup schedule, see Schedule Backups.

  4. Click OK to close the Backup Options dialog box.

Archive Log Backups

Use log backups in the following scenarios.

  • To restore the database to the most recent state after a database failure.
  • To restore specific logs, which are identified using a serial number or identification tag that are missing in the database.
  • To restore logs from a specific time range that were lost due to a hard disk corruption. Use a point-in-time archive log restore.

The current redo log file is closed (even if it is not filled up completely) and the next redo log file is used for writing using a log switch during an archive log backup. The closed redo log file is then archived during the log phase.

Procedure

  1. From the CommCell Browser, expand Client Computers > client > Oracle > instance.
  2. Right-click the subclient configured for the archive log backup and then click Backup.
  3. On the Backup Options for Subclient dialog box, select the backup type and initiation:
    1. In the Backup Type section, choose the backup type.
    2. If you selected the Cumulative check box, specify the backup incremental level in the Oracle Incremental Level box.
    3. In the Job Initiation section, specify whether to run the backup now or if it will be scheduled.

      Note: If you selected Schedule, set up the schedule.

      For information on configuring a backup schedule, see Schedule Backups.

    4. Click Advanced.

      The Advanced Backup Options dialog box appears.

  4. Select the option to determine the logs to back up and delete.

    On the Backup Archive Logs tab, and Delete Archive Logs tab:

    Select the Delete Archive Logs check box and Backup Archive Logs check box.

    Choice Description
    All Backs up or deletes all logs
    Older than n Days Backs up or deletes logs older than the specified number of days
    Not Older than n Days Backs up or deletes logs not older than the specified number of days
    By Log Time Backs up or deletes logs in the specified time range.

    Select the Start Time and End Time check boxes and enter the start and end times of the logs.

    If you only specify the start log time, all logs are backed up from the start time to the current time.

    By Log Seq Num Backs up or deletes logs in a specified sequence range.

    The 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 number1. When the first file fills, Oracle switches to the second file and assigns a log sequence number of 2.

    Select the Start Sequence Number and End Sequence Number check boxes and enter the beginning and ending sequence numbers

    By Sys change Num Backs up or deletes logs in the specified System Change Number range.

    The 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 committed transactions could be 576601 and 576799.

    Select the Start Sys chg Num and End Sys chg Num check boxes and enter the beginning and ending SCNs:

    The end serial number must be greater than or equal to the start serial number. •

    The start and the end SCN cannot be 0.

    If you provide only the start SCN, is the only one provided, only the logs starting that start from that sequence number are backed up.

    Like Backs up or deletes logs with a file name that starts with a specified string.

    Enter the string to match.

    Not Backed up Backs up or deletes logs that have not been backed up a specified number of times.

    Enter the number of times a log must be backed up.

  5. On the Backup Archive Logs tab, specify the location where the backed up logs are stored:
    1. Select the Archive Log Destinations for Backup check box.
    2. Click Add.
    3. On the Select an Archive Log Destination dialog box enter the full path to the directory where backed up archive logs will be stored.
    4. Click OK to close the Select an Archive Log Destination dialog box.
  6. Click OK to close the Advanced Backup Options dialog box.
  7. Click OK to close the Backup Options dialog box.

IntelliSnap Backup on NFS Volume

You can perform a IntelliSnap backup for Oracle when the database is on a NFS Volume. However, you will require a root access in the storage device's NFS configuration to be able to read and write on the accessible Oracle files i.e., the host on which the NFS Volume is mounted.

You can also perform IntelliSnap backups for Oracle if the database resides on a Direct NFS volume. IntelliSnap backups supports volumes using the Oracle Direct NFS (dNFS) protocol.

File level revert is performed by default when revert restore is run on NFS volumes. For Volume Level revert on NFS volumes, use the sUSE_FILE_LEVEL_REVERT registry key. File level revert cannot be performed when the database resides on regular SAN Volumes (LUNs).

Consider the following while performing an IntelliSnap backup for data or databases that reside on an NFS Volume:

  • The export name on the storage device should be the same as the storage path on the storage device.

    E.g., if the storage path of the storage device is /vol/Volume/Qtree, use /vol/Volume/Qtree as the export name and not an alias such as /ExportName.

  • You can use the exports both at the root of a NetApp volume and at subdirectory levels below the root of the volume.
  • Make sure that the storage device is accessible from the source and proxy machine (even if they exist in different domains) using the storage device's short name while mounting NFS exports from the storage device. Make sure to enter the storage device credentials using its short name. Do not use an IP address or the fully qualified domain name.

    E.g., use a short name for the server such as server1 or server2.

Enabling Volume Level Reverts on NFS Volumes

  1. From the CommCell Browser, navigate to Client Computers.
  2. Right-click the <Client>, and then click Properties.
  3. Click Advanced and then click Additional Settings tab.
  4. Click Add.
  5. In the Name field, type sUSE_FILE_LEVEL_REVERT.

    The Category and Type fields are populated automatically.

  6. In the Value field, type N.
  7. Click OK.

Marking Backups with a Unique Identification Tag

You can configure tags for backups to uniquely identify a particular RMAN backup copy. These tags can be used later during restore operation to restore from a specific backup. Note that the tag defined at the backup job level will override the tag defined at the subclient level.

For a Specific Backup

  1. From the CommCell Browser, navigate to Client Computers | <Client> | Oracle | <Instance>.
  2. Right-click the <Subclient> and click Backup.
  3. Click Advanced.
  1. Click the Oracle Options tab.
  2. In the Backup Tag box, type the tag name.

    For Example, weekly_backup.

  3. Click OK.

For All Backups

  1. From the CommCell Browser, navigate to Client Computers | <Client> | Oracle | <Instance>.
  2. Right-click the <Subclient> and click Properties.
  3. on the Advanced Backup Options dialog, navigate to the Advanced tab.
  4. In the Backup Tag box, enter the tag name.
  5. Click OK.
