Name

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

Backup Type

Device Type

Data carrier type

Backup Tool

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

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

Device/File

Depending on the backup type enter the required information:

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.

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

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.

FILE

Do not create backups on data carriers of the FILE type that are located on the same hard disk as the volumes of the database. Always back up to a separate hard disk.

If your data carriers are located on the same computer as the database, regularly copy the backups to other computers or data carriers using operating system commands.

TAPE

You can use autoloaders.

Do not use tapes more often than is recommended by the manufacturer.

Unix:

PIPE

On Microsoft Windows, the pipes are created by the database kernel.

On Unix, the pipes are not created by the database kernel:

Before you carry out a log backup to a pipe without a third-party backup tool or with a third-party backup tool not directly supported by SAP MaxDB, first set the value of the special database parameter EnableLogBackupToPipe to YES. This ensures that the system can overwrite the log entries in the log area that have already been written to the pipe. Note that the system does not check whether the log backup to the pipe was successful. More information: Database Administration, Special Database Parameters
