Starting with Oracle 11g, Oracle extended the ASMCMD command to include ASM disk group metadata backup and restore functionality.<\/p>\n

For a list of all commands added with 11g, take a look at the following MOS Note: ASMCMD \u2013 New commands in 11gR1 (Doc ID 451900.1)<\/p>\n

The ASMCMD md_backup and md_restore commands provide the ability to recreate a pre-existing ASM disk group with the same disk paths, disk names, failure groups, attributes, templates and alias directory structure. In 10g you have to manually recreate the ASM disk group and any required user directories\/templates. In 11g or newer we can take backup of ASM diskgroup metadata.<\/p>\n

The md_backup command creates a backup file containing metadata for one or more disk groups. By default all the mounted disk groups are included in the backup file which is saved in the current working directory.<\/p>\n

Backup the ACFS Disk Group metadata.<\/p>\n

This example backs up all of the mounted\n        disk groups and creates the backup image in the\n        \/scratch\/backup\/alldgs20100422 file. The second example creates a\n        backup of DATA disk group. The backup that this example creates is\n        saved in the \/scratch\/backup\/data20100422 file. The third example\n        creates a full disk group backup. This example backs up all of the\n        mounted disk groups, volumes and file system that are visible on\n        the current node and created the backup image in the given path.\n        The forth example creates a full backup of disk group, volume and\n        file system including file system security, encryption and audit\n        attributes. The fifth example creates a backup of DATA disk group.\n        This example starts DATA disk group backup and detects a volume\n        with DRL (Disk group Recovery Log) and it adds DATADRL disk group\n        to backup.\n\n        ASMCMD [+] > md_backup \/scratch\/backup\/alldgs20100422\n        Disk group metadata to be backed up: DATA\n        Disk group metadata to be backed up: FRA\n        Current alias directory path: ORCL\/ONLINELOG\n        Current alias directory path: ORCL\/PARAMETERFILE\n        Current alias directory path: ORCL\n        Current alias directory path: ASM\n        Current alias directory path: ASM\/ASMPARAMETERFILE\n        Current alias directory path: ORCL\/DATAFILE\n        Current alias directory path: ORCL\/TEMPFILE\n        Current alias directory path: ORCL\/CONTROLFILE\n        Current alias directory path: ORCL\/ARCHIVELOG\/2009_07_13\n        Current alias directory path: ORCL\/BACKUPSET\/2009_07_14\n        Current alias directory path: ORCL\/ARCHIVELOG\/2009_07_14\n        Current alias directory path: ORCL\n        Current alias directory path: ORCL\/DATAFILE\n        Current alias directory path: ORCL\/ARCHIVELOG\n        Current alias directory path: ORCL\/BACKUPSET\n        Current alias directory path: ORCL\/ONLINELOG\n\n\n        ASMCMD [+] > md_backup \/scratch\/backup\/data20100422 -G DATA\n        Disk group metadata to be backed up: DATA\n        Current alias directory path: ASM\/ASMPARAMETERFILE\n        Current alias directory path: ORCL\/DATAFILE\n        Current alias directory path: ORCL\/TEMPFILE\n        Current alias directory path: ORCL\/CONTROLFILE\n        Current alias directory path: ORCL\/PARAMETERFILE\n        Current alias directory path: ASM\n        Current alias directory path: ORCL\n        Current alias directory path: ORCL\/CONTROLFILE\n        Current alias directory path: ORCL\/DATAFILE\n        Current alias directory path: ORCL\/ARCHIVELOG\n        Current alias directory path: ORCL\/BACKUPSET\n        Current alias directory path: ORCL\/ONLINELOG\n\n\n        ASMCMD [+] > md_backup \/scratch\/backup\/data20100422\n        Disk group metadata to be backed up: DATA\n        ADVM metadata to be backed up: VOL1\n        ADVM metadata to be backed up: VOL2\n        ADVM metadata to be backed up: VOL3\n        ACFS metadata to be backed up:\/mountfs\/fs1\n        ACFS metadata to be backed up:\/mountfs\/fs2\n        ACFS metadata to be backed up:\/mountfs\/fs3\n\n\n        ASMCMD [+] > md_backup \/scratch\/backup\/data20100422 --acfs_sec_encr\n        Disk group metadata to be backed up: DATA\n        ADVM metadata to be backed up: VOL1\n        ADVM metadata to be backed up: VOL2\n        ADVM metadata to be backed up: VOL3\n        ACFS metadata to be backed up:\/mountfs\/fs1\n        ACFS metadata to be backed up:\/mountfs\/fs2\n        ACFS metadata to be backed up:\/mountfs\/fs3\n\n\n        ASMCMD [+] > md_backup \/scratch\/backup\/data20100422 -G DATA\n        Disk group metadata to be backed up: DATA\n        ADVM metadata to be backed up: VOL1\n        ADVM metadata to be backed up: VOL2\n        ADVM metadata to be backed up: VOL3\n        ACFS metadata to be backed up:\/mountfs\/fs1\n        ACFS metadata to be backed up:\/mountfs\/fs2\n        ACFS metadata to be backed up:\/mountfs\/fs3\n        Disk group metadata to be backed up: DATADRL\n        ADVM metadata to be backed up: DRLVOL3\n        ADVM metadata to be backed up: VOL5\n        ACFS metadata to be backed up:\/mountfs\/fs4\n        ACFS metadata to be backed up:\/mountfs\/fs5\n<\/pre>\n

Conclusion<\/h3>\n
The ASMCMD md_backup and md_restore is a very useful feature which helps you re-creating the ASM structure. But be careful, it restores only the metadata, not the data itself.<\/p>\n","protected":false},"excerpt":{"rendered":"
Starting with Oracle 11g, Oracle extended the ASMCMD command to include ASM disk group metadata backup and restore functionality.
