Before you can back up data and redo log entries to a data carrier, you must a backup template.

Backup Template Properties

Property

Description

Name

The name of the backup template has no influence on the name of the backup created later using this backup template.

Backup Type

  • Complete data backup

  • Incremental data backup

  • Log backup

Device Type

Data carrier type

  • File

  • Tape

  • Pipe

Backup Tool

If you are using a backup tool from a third-party provider, specify the abbreviation for your backup tool:

  • BACK: Backint for Oracle/Backint for MaxDB

  • NSR: Networker

  • TSM: TSM

More information: Database Administration, Using Backup Tools from Other Providers

Device/File

Depending on the backup type enter the required information:

  • Name of the tape device in the operating system

  • Path and file name of the file in the file system

  • Path and name of the pipe

We recommend that you do not use the same data carrier for several databases.

For log backups to files, the system adds a sequence number to the name of each new backup file. It assigns the numbers sequentially as long as the history of the log backups is not interrupted. If the log backup history is interrupted (for example after the database was initialized), the system begins numbering at 001 again.

It also uses sequential numbers if you carry out multiple log backups for one database onto different data carriers, and thus to files with different file names.

Example Example

LogUri.001

LogKai.002

LogOleg.003

LogUri.004

LogUri.005

End of the example.

If automatic log backup is switched on, the system stores all backup files under the same file name using a sequence number.

Example Example

DEMODB_MYLOG.001

DEMODB_MYLOG.002

DEMODB_MYLOG.003

DEMODB_MYLOG.004

DEMODB_MYLOG.005

End of the example.

You can also back up to data carriers on remote computers. More information: Database Administration, Backing Up and Restoring Data with Remote Computers

Size

There is no size restriction in default mode.

The size of log backups to files is calculated as the size of a log segment (general database parameter AutoLogBackupSize) plus the space required by system information.

More information: Database Administration, General Database Parameters

Overwrite

If you want to back up to a file and use this file more than once, define the backup template so that the data carrier can be overwritten. If you use this type of backup template for backups, the system overwrites old backups with new backups.

We recommend that you do not overwrite a backup with the backup that immediately follows it. Always keep an older version of the backup.

Block Size

Block size that the system uses to write backups to the data carrier.

Autoloader

Select this option if you want to use a tape device with an automatic tape loader.

OS Command

Operating system commands for backing up to tape devices.
