Operating Systems AIX AIX 7.2 MKSYSB Backup and Restore Best Practices? Post 303034058 by rbatte1 on Wednesday 17th of April 2019 11:55:12 AM

Excellent. Good to know you are sorted.

Just to clarify, I do mean DVD-RAM . A ROM would be Read Only (hence the O)

It's different to DVD-RW & DVD+RW and there is a bit of discussion on a Wikipedia page : DVD-RAM - Wikipedia
To get it all to work, we had to make a mksysb image on a local disk and then use mkdvd appropriately. Oddly it eventually calls readcd with the write flag set, but you probably won't need to worry about that. It did need a chunk of free space in the rootvg too, just over twice the size of the mksysb image. I also had to adjust the LV creating algorithm in mkdvd (I think) because it estimated too small and we were continually running out of space in the temporary LVs it creates.


Is there anything else we can try to help with?

Pretty penny's. Just remember that mksysb and savevg are just front-ends for backup.

Ignoring that rootvg also creates files needed to boot a system... (1 Reply)

NAME
dares - rescue files from damaged CDs and DVDs SYNOPSIS
dares -i image -s path [-h2i h2i_file] [-a] [-m] [-llogfile] dares-qt [-i image] [-s path] [-h2i h2i_file] [-a] [-m] [-llogfile] DESCRIPTION
Dares scans a CD/DVD image or a CD/DVD and tries to find files. It does not depend on filesystem information, but instead uses the Magic library to identify files. Doing it this way Dares can recover files even when the filesystem (ISO-9660 or UDF) on the disc is damaged and cannot be mounted anymore. Dares can use H2cdimage (ftp://ftp.heise.de/pub/ct/ctsi/h2cdimage.zip) files to rescue data from heavily damaged optical discs. OPTIONS
-i CD/DVD image file or device. -s Directory where the rescued files shall be stored. -h2i Optional h2i file for the CD/DVD image. -a Store all found files without any user interaction. -m Use Mime types instead of a description. -l Logfile (default: dares.log) AUTHOR
dares was written by Oliver Diedrich <odi@ct.heise.de>. This manual page was written by Michael Hanke <michael.hanke@gmail.com>, for the Debian project (but may be used by others). Michael Hanke Oktober 2005 DARES(1)
