operation. Use Unix commands to determine the size of the following
partitions:
• /
• /boot
• /var
• /IMS
• /usr
Backup requires approximately 20 minutes per GB when using a USB
tape drive, and approximately eight minutes per GB for a SCSI tape
device.
Restore requires approximately 35 minutes per GB, regardless of which
type of tape drive is used.
Estimates for backup and restore are rough as there are multiple factors
that can affect the time required to complete the operation. As backups
can be performed while the machine is live, system activity may slow
the operation. If a backup or restore occurs across a network, network
traffic can affect the time required to complete the operation.
Remote tape drive set up
A remote tape drive is required. The following procedure outlines the
steps necessary to properly set up the remote tape drive if it is on an
MCP Server.
If the remote tape drive is NOT on a MCP Server, you may skip this
procedure. However, the user must ensure the remote shell operations
from the server to be backed up are enabled on the remote tape drive
server.
From the terminal server
1 As the MCP Server has to access the tape drive on the remote
host, make sure it has the proper access to that host.
2 Log in as sysadmin to the server with the tape drive.
3 Enable the execution of remote shell commands.
sudo /usr/local/bin/mcp_enable_remote_sh.pl
<MCP_Server_IP>
<Enter>
where <MCP_Server_IP> is the Portal Host IP address.
4 From the Portal, log in as root .
5 Verify access to the remote host has been set correctly.
