Be very careful as GNU tar is buggy and does not always like to read |
| 12 |
continuation volumes from multi volume archives. This is extremely nasty as |
| 13 |
you will realize the problem once it is too late. |
| 14 |
|
| 15 |
GNU tar also does not support to archive all meta data from Linux. |
| 16 |

I recommend to use star. Star implementes reliable multi volume support and |
| 18 |
archives all meta data that is available on Linux. Only a reliable multi volume |
| 19 |
support inside the archiver allows you to read back archives starting past |
| 20 |
volume#1. |
| 21 |
|
| 22 |
Note that star also implements a nice true incremental backup feature that |
| 23 |
does not need additional data while creating backups. There is a database |
| 24 |
for old and new inode numbers in incremental restore mode. |
| 25 |
|
| 26 |
Check the star man page for examples on backups and incremental backups. |
| 27 |
|
| 28 |
Use tsize=4200k -multivol to tell star to write archives with multi volume |
| 29 |
information that split files across volumes. |
| 30 |
|
| 31 |
Use mkisofs to create a ISO filesystem (hve a look at the -stream-media-size |
| 32 |
option. |
| 33 |
|
| 34 |
Use cdrecord to write the ISO file to DVD. |
