1.  I want to backup the Root, Var or the Document Library to Tape.  I can boot from the Ultra 10 hard disk

Situation:
The customer wants to backup one or all of the Ultra 10 slices using the Backup Restore Utility

Solution:
The three slices that can be backed up with the Backup Restore utility are;
 

Name
Mount point
Root
/
var
/var
Document Library
/var/spool/kodak_library/DocumentStorage
              
1.  Insert your magnetic tape into the tape drive

2.  Start the Backup/Restore software by any method below

Right click on the Open Windows Desktop
Right click on printer
Left click on Backup/Restore Login
or
su to root
type system_admin.adm

3.  Right click on Edit and choose Add Backup

4.  Here is a description of each of the options;
Mount Directory        This is where you choose the slice to backup.  For now Select Document Library
Tape Device              Leave it at Travan NS (TM) Compressed
Tape Drive                Location First external Tape drive
Tape Drive                Local.  A remote backup is possible but I havent learned that yet
Backup Level            Full.  In this example we are doing a full backup
Tape Position            Leave at 1.  Use this to index multiple backups onto a single tape
When                       Use this to select when to do a backup.  For now choose Now

(Device Name, Blocking Factor, Tape Density, Tape Length  Need not be touched)

5.  Double check your settings and click apply

6.  A new command tool should start automatically.  Here is what our backup log appears like

  DUMP: Writing 32 Kilobyte records
  DUMP: Date of this level 0 dump: Wed Mar 06 13:43:08 2002
  DUMP: Date of last level 0 dump: the epoch

  DUMP: DUMP IS DONE
  DUMP: Level 0 dump on Wed Mar 06 13:43:08 2002

Hit [Return] to continue

7.  Hit return and close the Backup/Restore Utility

Way to go.  You have successfully backed up the Document Library to tape.


2.  I want to backup the Document Library to Tape.  I cannot boot from the Ultra 10 hard disk

Situation:
The customer may or may not have been backing up their Document library to tape.
The Ulta 10 has suffered a major crash.  They can no longer boot from the hard disk.   (Eeek)
You want to backup the Document Library to tape, re-install system software and restore the Document Library from tape

Solution:
You must boot the Ultra 10 from the System Software CD.  Have it ready

Get the Ultra 10 to the OK prompt by any of these methods
    Power on the machine and use Stop a early in the boot sequence  (Be carefull)
    If the machine is already partially booted, try init 0

Put the System Software CD in the CDROM drive

At the OK prompt, type boot cdrom -s.  Wait for to machine to boot to the # prompt

Type the following commands;

# fsck /dev/rdsk/c0t0d0s4                This will run a File system check on slice 4, the document library
# mount /dev/dsk/c0t0d0s4 /mnt       This will mount this device on a mount point called /mnt
# ufsdump 0cf /dev/rmt/0 /mnt           This will run the Unix file system dump command.  0 Entire file system
                                                         c Sets defaults for cartridge  f Use dump_file rather than /dev/rmt/0
# umount /mnt                                   Unmount the /mnt
# init 0                                               Back to OK prompt
# boot cdrom - install                         Begin the System Software install process

After installing System Software, use the Backup Restore Utility to restore from your tape.


3.  I want to restore the Document Library from tape with the Backup/Restore software

Situation:
The customer wants to restore the entire Document Library from tape

Solution:
1.  Start the Backup/Restore software by any method below

Right click on the Open Windows Desktop
Right click on printer
Left click on Backup/Restore Login
or
su to root
type system_admin.adm

2.  Right click on Edit, choose Restore.

3.  Here is a description of the options
 Tape Device                     Leave this at Travan NS (TM) Compressed
 Tape Position                   Use this to access any indexed backups you have.  Normally left at 1
 Tape Drive Location         First external Tape drive
 Tape Drive  Local.            A remote backup is possible but I havent learned that yet
 Restore Path                     You must type the Restore path (Mount point) here  (IE /var/spool/kodak_library/DocumentStorage)

The trickiest part of this procedure is the Restore Path

Here is a quick method

     1.  su to root
     2.  Type du.  Here is an example

/                     (/dev/dsk/c0t0d0s0 ):  815098 blocks   390748 files
/proc              (/proc             ):       0 blocks     3829 files
/dev/fd            (fd                ):       0 blocks        0 files
/var                  (/dev/dsk/c0t0d0s3 ): 5858014 blocks   505574 files
/var/spool/kodak_library/DocumentStorage(/dev/dsk/c0t0d0s4 ): 6583628 blocks   418135 files
/tmp               (swap              ): 1034112 blocks    41564 files

     3.  Highlight the path you want  (IE /var/spool/kodak_library/DocumentStorage)
     4.  Select copy on the Ultra 10 keyboard
     5.  Go back to the Restore Window, and use paste on the Ultra 10 keyboard

4.  Select Restore Entire Tape, and choose yes at the pop up window

A new command tool should start automatically.  Here is what our backup log appears like

extract file ./LIB/aaaaad/aaaaaw/Settings/scan.set
Add links
Set directory mode, owner, and times.
Check the symbol table.
Check pointing the restore

Hit [Return] to continue

Important Note:
A restore from tape will overwrite files and folders in the Document Library if the same file and folder names already exist
A restore from tape will not overwrite files and folders in the Document Library if different file and folder names exist


4.  I want to backup/restore with the Backup/Restore software using tape indexes

Situation:
The customer wants to perform multiple backups to 1 tape using indexes

Solution:
The procedure to do this is exactly the same as in "I want to backup the Root, Var or the Document Library to Tape" from above
In this case however, adjust the "Tape Position" setting to reflect the "Index" position you wish to store the next slice
For example, you may want to store the Document Library on index position 1 and /var on index position 2
The rest is of the procedure is pretty easy.

You can check the existing indexes on the tape by following these steps

1.  Start the Backup/Restore software by any method below

Right click on the Open Windows Desktop
Right click on printer
Left click on Backup/Restore Login
or
su to root
type system_admin.adm

2.  Right click on Edit, choose Index Tape and then Apply
You should see a list of the index number and backup name
Make sure you label your tape !!


5.  I am getting the error Tape Device /dev/rmt/xxx not known.  I need help
Perhaps the device number is different than what the GUI is allowing you to use... try this
Put a tape in the bay
#mt -f /dev/rmt/n status
Change n (The Drive Number) to 1,2,3 ... until you get feedback from the mt command indicating some tape information

ie Vendor 'TANBERG' Product 'NS20 Pro 20 GB' tape drive ...

If you enter the wrong drive number, you will get "No such device or address"
Once you have confirmed the driver number, change the GUI's tape device to other and change the Device name to reflect the changed drive number
IE /dev/rmt/0hn to /dev/rmt/1hn



6.  I'd like to see some other usefull mt commands

mt - Magnetic tape manipulating program
mt -f /dev/rmt/n    erase            Erases entire tape.  Be carefull
mt -f /dev/rmt/n    rewind          Duh.
mt -f /dev/tmr/n    retension       Full wind forward and back
