How can a QNX4 hard drive be backed up? Are there any utilities available?
|
| Solution |
There are two methods of making a hard disk backup in QNX4.
Method 1:
Use software provided in the contributed software section (/usr/free). There is a utility that is located in
http://www.qnx.com/cgi-bin/dir_find.cgi?/usr/free/qnx4/os/utils/disk/
or on quics.qnx.com (telnet/ftp).
/usr/free/qnx4/os/utils/disk/QNX_drive_copy.gz
and
/usr/free/qnx4/os/utils/disk/QNX_drive_copy.gz.readme
*****************************************************************************
NOTE:
QNX (QSSL) did not make this utility so QNX cannot offer any support for this
if any is needed. You may need to create a new .boot image so that the drive
will properly boot.

Method 2:
Raw disk copy, this will copy all partitions on the drive.
Things needed for this to work:
- The exact same drive that is currently in the system (size, make, model, everything).
1. Install the drive as a slave to the master, or in a SCSI system simply install it, but don't boot from it.
2. Once installed, check to make sure that the drive has been recognized by QNX. Type
"ls /dev"
after logging in and you should see a hd0 or hd0.0 and if the drive was detected there will be a hd1 or hd1.0.
3. Type from the commandline
"cp /dev/hd0 /dev/hd1"
This will copy everything on that drive, partition tables, etc onto the second drive (the one you just installed).
*****************************************************************************
NOTE: If you are planning on relocating the drive to a different computer
remember that you may need to recreate the .boot image for that particular
system. See Chapter 2 "Building an OS Image" on how to create a new image
for the system.
