Save time in backing up Joyent Smart Data Center

One does not frequently backup the head node USB key with Joyent's Smart Data Center. Generally you do it prior to upgrades. Therefore, its commonly a "do it twice" process as it has a quirky bug with regards to terminal emulation that I never seem to remember until its too late:

[root@headnode (CIS:0) ~]# sdc-backup -U c2t0d0p0

Disk c2t0d0p0 will relabled, reformatted and all data will be lost [y/n] y

labeling disk

creating PCFS file system

mounting target disk c2t0d0

mounting source disk c0t0d0

copying files

setting up grub

Sorry, I don't know anything about your "xterm-256color" terminal.

Error: installing grub boot blocks

Yep, my OSX default xterm-256color is not known, and the many-minutes long backup process dies at the end. To address this, override the terminal setting in root user's .bash_profile file with the line:

 export TERM=vt100

Simple, but its not every day you can increase performance by 50%, so to speak.
