Using the USB Removable Disk Drive for backup and restore

The disk drive is a backup and restore device that can be used as an alternative to tape drives. The removable disk drive is not

a replacement for regular disk drives and cannot be used as part of a disk array.

Note: If power is lost during a backup to the disk, the data can be compromised. Verify the data or rerun the backup.

Using the drive with AIX

AIX names the drive usbmsx. For example, usbms1 and usbms2. AIX also can use the device as a raw device. For example,

rusbms1 and rusbms2.

AIX uses the removable disk drive differently depending on the program being used. The AIX mksysb command builds a list of

ﬁles to back up, creates a universal disk format (UDF) ﬁle system, and puts a boot image and the root volume group on the

removable disk drive. When the mksysb process is complete the removable disk drive can be used to boot the system. If you

mount the removable disk drive, you can display and copy ﬁles to and from the UDF ﬁle system on the removable disk drive.

The AIX tar, backup, restore, dd, and cpio commands can write to the removable disk drive as a raw device or non raw device.

You might get improved performance by using the device as a raw device.

See the AIX documentation for additional information.
