Backing up/restoring systems in the partitions Functions of the System Management Console

4.6.2 Data backup

This description assumes a system disk of a partition which is backed up using a tape

device (DAT drive) which is connected to the system console (SMC).

Backing up a file system

A file system is backed up with the command ufsdump.

The following description shows how the file system is backed up on the tape device of the

SMC with ufsdump.

Preparations

1. You can determine in the partition the disk device name of the relevant file system as

follows:

a) Display the contents of the file /etc/vfstab.

# more /etc/vfstab

b) Determine and note the name of the file system in the column mount point. Check

the disk device name of the system disk (in the column device to mount).

Additional products which may be used, such as Solstice Disk Suite™, Veritas

LVM™ or EMC Powerpath™, must be taken into account.

2. Determine the number of tapes needed for data backup:

a) Log on as the system administrator.

b) Execute the command ufsdump S to obtain the size of the backup file in bytes:

# ufsdump S filesystem

c) Divide the predicted number of bytes by the storage capacity of a tape to determine

the number of tapes required.

Cartridges of the type “SONY Cartridge DGD-150P DAT-Tape DDS4“ with a length

of 150 m and a capacity of 20 GB are used by default in the SX server.

3. Create the data backup plan.

4. To allow the SMC the remote shell function or a remote login, enlist the server and the

user ID root in the file /.rhosts of the server to which the tape device is connected.

As an alternative, also keys can be used in the framework of the Secure Shell.

Example: <partition-name> root
