Managing the AMASS File System

3-156 Command Reference 6-00028-01 Rev A

Practical Application

The following example uses this command to back up files, in

optimized order, from a volume to a tape. AMASS backs up

entire files, even if they span media. Both scenarios assumes the

AMASS mount point is /archive.

Using cpio Command

Step 1. Log in as either amass or root.

Step 2. Enter the commands as shown in the following

example.

Step 3. When AMASS backs up partialfile, which

starts on volume 2 and is appended onto volume 3,

AMASS switches the media in the drive to back up

the remainder of partialfile on volume 3.

AMASS then reloads Volume 2 so it can continue

the backup process.

# su root

# cd /archive

# volfilelist 2 | sort -n +1 +2 | awk ’{print $1}’ | \

cpio -oc >/dev/rmt/0m

Lists all files on volume 2.

Prints just the file names.

Backs up the files to a tape

loaded in drive /dev/rmt/0m.

Numerically sorts files based

first upon volume, then based

upon logical block address.
