Sarge - how to write a filesystem backup directory to a DVD ?
Having gotten a new internal DVD burner, I'd like to know the best way to burn a directory of files to a DVD for system backup. (Also, I'd rather burn the DVD using a command at the BASH prompt instead of from a GUI.) The capacity of the DVD is 8gb, write speed is 16x, and the size of the directory to be burned to the DVD is about 7gb so there should be plenty of space. I've installed dvd+rw-tools from the Sarge CD's. I'm a little confused - should the input to growisofs be the directory that is to be burned to the DVD, or should an .iso be created first, and that in turn burned to the DVD, as is done with CD's ? I've seen references to formatting or initializing DVD's on a few websites but don't know if that's really necessary. A URL with a step by step sequence of how to do this or troubleshoot this would be appreciated. =Keith (FWIW, Here is the output of dvd+rw-mediainfo:) sudo dvd+rw-mediainfo /dev/hdd Password: INQUIRY:[DVDRW ][DRW-5S163 ][YSG1] GET [CURRENT] CONFIGURATION: Mounted Media: 1Bh, DVD+R Media ID: RICOHJPN/R03 Current Write Speed: 16.0x1385=22160KB/s Write Speed #0:16.0x1385=22160KB/s Write Speed #1:12.0x1385=16620KB/s Write Speed #2:8.0x1385=11080KB/s Write Speed #3:6.0x1385=8310KB/s GET [CURRENT] PERFORMANCE: Write Performance: 6.4x1385=8864KB/[EMAIL PROTECTED] - 0] Speed Descriptor#0:00/0 [EMAIL PROTECTED]/s [EMAIL PROTECTED]/s Speed Descriptor#1:00/0 [EMAIL PROTECTED]/s [EMAIL PROTECTED]/s Speed Descriptor#2:00/0 [EMAIL PROTECTED]/s [EMAIL PROTECTED]/s Speed Descriptor#3:00/0 [EMAIL PROTECTED]/s [EMAIL PROTECTED]/s READ DVD STRUCTURE[#0h]: Media Book Type: A1h, DVD+R book [revision 1] Legacy lead-out at:2295104*2KB=4700372992 READ DISC INFORMATION: Disc status: blank Number of Sessions:1 State of Last Session: empty Number of Tracks: 1 READ TRACK INFORMATION[#1]: Track State: blank Track Start Address: 0*2KB Next Writable Address: 0*2KB Free Blocks: 2295104*2KB Track Size:2295104*2KB ROM Compatibility LBA: 262144 READ CAPACITY: 1*2048=2048 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Honestly, RTFM of growisofs helps reducing your confusion. It runs mkisofs itself and catches the output. So it is not neccessary to make an iso image, you specify the same things you would do with mkisofs, eg. a directory, multiple directories, or graft-pointed catalogue. For big directories, the dirsplit utility can be used (from www.freshmeat.net, the one in Sarge is not uptodate). I've seen references to formatting or initializing DVD's on a few websites but don't know if that's really necessary. Unless you are going to use the UDF filesystem (writting on-the-fly) formatting should not be necessary. Free Blocks: 2295104*2KB Track Size:2295104*2KB Looks like a usual 4.3GiB medium.

I know this is not exactly what you are asking, but may I suggest that you take a look at mondo. It is a suite of tools for making self contained backups. It uses many existing tools like cdrecord as backends to accomplish necessary tasks. It has a simple and intuitive ncurses based semi-graphical front end. It is possible to make a complete backup on a set of bootable CDs or DVDs. The defaults are reasonable. You can create a complete backup of your system by hitting enter a few times and feeding it disks when it asks. It is also possible to run mondo from the command line, lending it to automated backups from cron, etc. You can take the disks to another machine, boot the first disk and restore your system. I did exactly that to migrate a sarge machine at work to a different box. The new/old box was a surplus Windoze machine. Different hardware, different disks, different everything. When I booted the first disk and told it to restore, it noticed that the partitions were different, asked if I wanted to repartition, and dropped me into fdisk. I set the partitions I wanted -- different from the old box -- and continued with the restore. Once the restore was done mondo noticed the new partition structure, asked if I wanted to fix lilo.conf, and dropped me into vim. I ran lilo, popped the last CD out and rebooted. Presto, I had my box up and running on a totally different set of hardware. I have heard people talk of bare-metal restores as a great and painful adventure. Thanks to the mondo suite, mine was totally painless. The actual backup and restore took a while writing and reading the CDs, but my actual interaction in each case was maybe five or ten minutes.

No, unless you're using DL media, the capacity of the DVD is approximately 4 gb. And you aren't finding any 16x DL discs yet, as far as I know. Your dvd+rw-mediainfo run below supports the fact that you only have 4gb discs. I'm a little confused - should the input to growisofs be the directory that is to be burned to the DVD, or should an .iso be created first, and that in turn burned to the DVD, as is done with CD's ? Pick one. The documentation for growisofs makes it plain from the examples that you can either specify the directory containing the files to burn (since it will call mkisofs as needed) or create an ISO yourself and burn that. I've seen references to formatting or initializing DVD's on a few websites but don't know if that's really necessary. Typically, +RW media needs to be formatted, also as documented. Usually, +R and -R do not. A URL with a step by step sequence of how to do this or troubleshoot this would be appreciated. Don't know what you need other than growisofs's man page. -- Marc Wilson | Respect is a rational process -- McCoy, The Galileo [EMAIL PROTECTED] | Seven, stardate 2822.3 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
