Option Description

source

Specifies the source file name.

destination

Specifies the destination file.

spbackup should be used when you want to make single or multiple backups of an SPFILE in the same or a different disk group without creating an SPFILE in the target disk group.

Note the following about the use of spbackup:

  • spbackup can back up an Oracle ASM SPFILE from a disk group to a disk group or to an operating system file.

  • spbackup can back up an Oracle ASM SPFILE from an operating system file to a disk group.

  • spbackup can back up an Oracle ASM SPFILE when the SPFILE is being used by an open Oracle ASM instance.

  • spbackup can make multiple backups of an Oracle ASM SPFILE in the same disk group.

spbackup does not affect the GPnP profile. The backup file that is created is not a special file type and is not identified as an SPFILE. This backup file cannot be copied with spcopy. To copy this backup file to and from a disk group, use the ASMCMD cp command.

To make a copy of a backup file in a disk group that is identified as an SPFILE file:

  1. Use the ASMCMD cp command to copy the backup file from the disk group to an operating system file. See "cp".

  2. Use the ASMCMD spcopy command to copy the operating system file to a disk group. See "spcopy".

Example

The following are examples of the spbackup command. The first example backs up the SPFILE in the data disk group. The second example backs up the SPFILE from the data disk group to the fra disk group.
