(re-)Creating a filesystem on the DVD-RAM disks

  • If you have a fresh blank DVD-RAM, this is optional with the "dd" method of writing an ISO image to the DVD-RAM disc. In this case /dev/hdd is the DVD-RAM device.

  • /sbin/mke2fs -b 2048 /dev/hdd
  • (Then be patient as this take a bit of time)

Backup of the only the Redhat Linux system area onto 4.5 Gig DVD-RAM disks using mondorescue 1.4x

Because we are using "dd" to write to the DVD-RAM device, it is OK for the DVD-RAM to be in IDE mode.

Trick here is to exclude the data directories using the -E option.

mondoarchive -g -m -s4280m -S /tmp -T /tmp -L -E "/web_disc /web_logs" \
-Oi -d /tmp/isos -A "dd if=_ISO_ of=/dev/hdd; rm -f _ISO_; eject /dev/hdd"

This should easily fit onto a single single-sided 4.5Gig DVD-RAM disk.

Refer to the CD-Restore (which is very similar) To restore from the DVD, either do an interactive restore, or just boot up the system with the DVD-RAM disc in the drive.

(caveates: for interactive partial restoring from backup DVD-RAM disks created with mondorescue 1.4x, the dvdram device should be aliased to /dev/cdrom: e.g, ln -sf /dev/hdd /dev/cdrom)

Backup web_logs onto 4.5 Gig DVD-RAM disks using mondorescue 1.4x

Because we are using "dd" to write to the DVD-RAM device, it is OK for the DVD-RAM to be in IDE mode.

Trick here is to only include the data directory on interest using the "-I" option.

mondoarchive -g -m -s4280m -S /tmp -T /tmp -L -I "/web_logs" -Oi -d /tmp/isos \
-A "dd if=_ISO_ of=/dev/hdd; rm -f _ISO_; eject /dev/hdd"

This should fit onto two single-sided 4.5Gig DVD-RAM disk.

(caveates: for interactive partial restoring from backup DVD-RAM disks created with mondorescue 1.4x, the dvdram device should be aliased to /dev/cdrom: e.g, ln -sf /dev/hdd /dev/cdrom)

Backup web_data onto 4.5 Gig DVD-RAM disks using mondorescue 1.4x

Trick here is to only include the data directory on interest using the "-I" option.

mondoarchive -g -m -s4280m -S /tmp -T /tmp -L -I "/web_disc" -Oi -d /tmp/isos \
-A "dd if=_ISO_ of=/dev/hdd; rm -f _ISO_; eject /dev/hdd"
