Backup-image operation

The backup-image operation creates an image backup of one or more volumes on your system.

  • Microsoft Windows Clients: These volumes can be formatted FAT, FAT32, or NTFS volumes, or unformatted RAW volumes. If a volume is NTFS-formatted, only those blocks used by the file system are backed up.
  • UNIX Clients:
    • For Linux clients, image backup is supported only on partitions with ID 0x83 or logical volumes created with the Linux Logical Volume Manager. Backing up other partitions, such as extended partitions that contain mounted file systems or database data can produce inconsistent backup data if the data changes during the image backup operation.
    • The usage of GPFS snapshot, and image backup is not supported for GPFS file systems on:
      • Linux x86/x86_64
      • Linux on POWER
      • Linux for IBM zSeries
