Restore file from backup (IMPORT)

Restore file from backup (IMPORT)

The IMPORT command imports or restores a cluster, AIX, or catalog from a backup created by the EXPORT. Here, the input is the backup created by EXPORT, and the output is like the base file from where the data was exported earlier.

//JOBNAME  JOB job-card-parameters
//STEP1    EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN    DD *
  IMPORT (entryname 
	 [FILE(ddname)]
	 [NEWNAME(newname)]
	 [ORDERED | UNORDERED]
	 [VOLUMES(volser[ volser...])])
    ({INFILE(ddname) | 
     INDATASET(dataset-name)}
	 [CATALOG(catname)]
	 [ERASE | NOERASE]
	 [PURGE | NOPURGE])
	[DEVICETYPE(type)]
	[VOLUMES(volser[ volser...])]
  	[CATALOG(catname)]

Mandatory Parameters

  • INFILE(ddname) - Specifies the DD name of the sequential dataset that contains the exported backup. This dataset should have been previously created using the EXPORT command. Short Description: IFILE
  • INDATASET(dataset-name) - Specifies the input DSN name of the sequential dataset that contains the exported backup. Short Description: IDS
  • NEWNAME(newname) - specifies the new name of an imported cluster, aix, its components, or a path.
  • VOLUMES (volser[ volser...]) - Specifies the volume serial numbers where the dataset will reside. If there is not enough space on the volume as specified, the allocation is unsuccessful. Short Description: VOL

Optional Parameters

  • FILE(ddname) - specifies the file name identifying the volume(s) and extents allocated to the data and index components of an aix or cluster to be imported.
  • ERASE | NOERASE - Default: NOERASE
    • ERASE - specifies the cluster components memory is to be erased with binary zeroes when cluster is deleted. Short Description: ERAS
    • NOERASE - specifies the cluster components memory is not to be erased when cluster is deleted. Short Description: NERAS
  • PURGE | NOPURGE -
    • PURGE - Specifies the output objects should delete if the retention period has not expired. Short Description: PRG
    • NOPURGE - Specifies the output objects should not delete until the retention period has expired. Short Description: NPRG
  • ORDERED | UNORDERED -
    • ORDERED - Specified volumes are to be used in the order they were listed in the VOLUMES parameter. Short Description: ORD
    • NOPURGE - Specifies volumes can be used in any order. Short Description: UNORD
  • CATALOG (catname) - Specifies the name of the catalog where the path will be defined. Short Description: CAT
