The iR 110/150 ufsdump/ufsrestore
Network Backup Page

Backing up (Dump)
1. The SCS is booted with a CD
2. The SCS mounts a directory on an NFS server
3. A script is executed which will do the following;
4. An fsck -y is performed on 3 partitions (slices)  (root, var and doc library)
5. A ufsdump is performed on the SCS's 3 slices (root, var and doc library)
6. The output of ufsdump is compressed with bzip2 and stored over the network to an NFS server
7. You are then requested to have a nice day

Restore
1. The SCS is booted with a CD
2. The SCS mounts a directory on a NFS server
3. A script is executed which will do the following;
4. Provide an interactive vtoc dump (writing a new partition layout to a disk)
5. The newly created partitions are formatted (newfs)
6. The 3 slices are decompressed with bzip2, piped through ufsrestore and written to the SCS hard disk
7. A bootblock is written to the disk
8. An fsck -y is performed on 3 slices  (root, var and doc library)
9. You are then requested to have a nice day

1. Easy distribution
Lets say we install System Software Version 5.01 on a 20GB hard disk for a iR150
We have three parition (slice) schemes to choose from.  Large Spool, 50/50 and Small Spool
The root partition remains the same size in all three of these schemes
It is the var and document library (doclib) slices that can vary in size
Although the sizes the of var and doclib slices can be different, the data written to them is the same in all 3 slice schemes
(IE the data written to the var slice is the same for either Large Spool, 50/50, or Small spool)
Here is the easy distribution part
I have installed System Software V5.01 for the iR150 with all the necessary patches.
Now using the scripts on this page,  I can create a dump of the root (slice0), var (slice3) and doclib (slice4) and put these dump files (images) on 2 CD's for distribution
Using the restore scripts also from this page, you can write these slice images to a iR110/150 using any partition scheme you want
You can use this at a fresh installation or as a backup solution
The restore script finishes within 20 minutes with no interaction !!

2. Less CD's for distribution
The dd backup method requires 6 CD's per distribution;
5.01 iR150 Large Spool       2 CD's
5.01 iR150 50/50                 2 CD's
5.01 iR150 Small Spool       2 CD's

The ufsdump/ufsrestore method requires only 2 cd's per distribution;
5.01 iR150 Any scheme      2 CD's

In case you get an old marking engine and need to flash it up, 3.15 and 4.32 fit on 1 CD !!

3. Speed
The dd backup method writes the entire disk, including empty space.
The ufsdump/ufsrestore method does not include empty space
The images will dump/restore faster


4. No need to zero the hard disk
The dd Network Backup solution will copy the entire disk, even 1's and 0's of old, useless data
Ufsdump only backs up valid, used data

Lets assume the following;
NFS Server IP is 192.168.10.50
The NFS server exported directory is /ir110
The SCS NIC hme0 is 192.168.10.100
The script files are in the /ir110 directory

A. Create the NFS
You must create a NFS server with read/write permissions so the iR110/150 SCS can upload files
I cant help you with NFS server configuration options here.  There are to many OS's and versions
Just ensure that 192.168.10.100 has read/write permissions


B. Boot SCS from OS CD
Use init 0 or whatever safe means to get the the ok prompt
Then type boot cdrom -s

 
C. Configure the SCS NIC and mount NFS
After the SCS boots up type the following
#ifconfig hme0 192.168.10.100                  (Gives the SCS's on board NIC (nearest to the video connector) an IP address)
#ifconfig hme0 up                                       (Brings this NIC interface up)
#mount 192.168.10.50:/ir110 /mnt      (Mounts the NFS directory /ir110 onto the mount point /mnt)


D.  Obtain, decompress and check the permissions of the ufsdump/ufsrestore scripts
You can get the ir110-ufsdump-scripts.zip file here
I zipped the two scripts to bypass IE download issues
Unzipping the file will reveal 2 scripts called "dump" and "restore"
You will also see several files with vtoc in the file name (more on this later)
Copy all the files to the NFS server's /ir110 directory
On the SCS, cd to the /mnt directory
You should be able to use ls and see the scripts you just copied

Now just to be safe, lets copy the scripts to the SCS's /tmp directory
#cp /mnt/dump /tmp                                  (Copies the script restore to the SCS under /tmp)
#cp /mnt/restore /tmp                                (Copies the script download to the SCS under /tmp)
#cd /tmp                                                   (CD to /tmp)

Now we have to check the permissions on the scripts
If you unzipped ir110-ufsdump-scripts.zip on a Dos/Windows machine the file permissions will be lost
If you unzipped ir110-ufsdump-scripts.zip on a Unix/Linux box, the permissions will not be lost

Do this procedure to check and change the permissions if required

Do a ls -la
Ensure root has execute permissions on the files "dump" and "restore" like the red x in this example
-rwxr--r--  1 root  wheel   222 Feb 27 22:12 dump
-rwxr--r--  1 root  wheel   214 Feb 27 22:12 restore

If you see this;
-rw-r--r--  1 root  wheel   222 Feb 27 22:12 dump
-rw-r--r--  1 root  wheel   214 Feb 27 22:12 restore
The red - indicates that root does not have execute permissions on these files

You will need to use chmod to change this
#chmod u+x dump
#chmod u+x restore

Do another ls -la to confirm the permissions are set correctly


E. Executing the scripts
From the /tmp directory, the scripts are executed as follows

To dump the SCS hard disk to an images called slice0, slice 3 and slice 4, type the following
./dump
The dump will take 1-2 hours to complete so please be patient


To restore these slice images to the SCS,  type the following
 ./restore
The restore process will take 20-30 minutes to complete

A very important part of the restore script is the writing of the vtoc file (Virtual Table of Contents)
The vtoc file is a simple text file that is to be written to the hard disk (kinda like a MBR or Master Boot Record in the PC world)
I have included several vtoc files for the 9GB and 20GB hard disks
The restore script will request you to choose the hard disk size and partition scheme you require
If all goes well, the vtoc is written to the disk
If you already have a partition or slice layout on the disk, simply choose “Skip this step and use the existing partition layout”

If the included vtoc files do not meet your needs or result in (error messages) dont worry.  See here
