There are a number of ways to back up your files onto some sort of secondary media. If you have a PC or Mac, you can transfer your data to floppies. Otherwise you can use the following method. Other methods are available via special arrangement with Sysgroup.
For this method, you will need 1/4" data cartridges. They come in several sizes, there are two common sizes available 450 ft (which will contain aproximately 45 Megabytes) and 600 ft (which will contain aproximately 60 Megabytes).
Each of the Tektronix 4319 workstations in both the CS terminal room and
the EE grad cad lab have a scsi tape drive. You can login to the 4319's
in the CS terminal room using the same login name and password you use
on rigel
.
To backup or restore files using a scsitape you will either need to use
tar
or cpio
. The devices for the scsitape are /dev/rmt8
if you want to have the tape rewind after you have tar
'ed or
cpio
'ed a file, or `/dev/rmt12' which will not rewind when the
tar
or cpio
command is done.
Tar
Method:
To backup files: tar -cvf /dev/rmt12 filenames To restore files: tar -xvf /dev/rmt12 filenames For table of contents: tar -tf /dev/rmt12
Cpio
Method
To backup files: echo filenames | cpio -V/dev/rmt12 -ovc To restore files: cpio -ivcd -V/dev/rmt12 For table of contents: cpio -ivct -V/dev/rmt12
For more information Read the tar
(1), cpio
(1), and mt(1)
manual pages.
Example
Using tar
:
% cd % ls file1 file2 file3 file4 % tar -cvf /dev/rmt12 file1 file2 file1 file2 % tar -tf /dev/rmt12 file1 file2
(Using cpio
)
% cd % ls file1 file2 file3 file4 % echo file1 file2 | cpio -V/dev/rmt12 -ovc file1 file2 % cpio -ivct -V/dev/rmt12 file1 file2
