Multi-DVD or (multi-CD) spanning backups with tar
Indeed, I never did trust either of the "tars".
I would like to just chime in with a tool with which I have had a successful relationship for over two years now.
It's hfspax, a modified version of the standard pax-utility to take on resource-forks properly.
To make a multipart backupfile you coud say something like this:
=write out mode
=verbose mode
=specifying the backupfile, because OSX does not support tape
=write the files in cpio-format. You can also choose from other formats, it' just my own preference
And now for the important part
=specifies the backupfile size. You can choose: M(egabytes), K(ilobyes)
When your backupfile reaches 4500Megabytes, you're prompted to give the new file a name. You must give it the same path as the first file, give it a logic name:
First file : /Volumes//backupfile_1
Second file : /Volumes//backupfile_2
You get the idea.
To restore:
use
then:
This will restore it all back to its former glory, resourceforks and all.
New this time is:
=read in mode
="preserve everything" - file permissions, mod.times, etc
=Normally hfspax overwrites everything in its way, this option make hfspax not overwrite existing files.
There are tons of other useful options, so go explore.

Interesting. Rather than combining the parts back together prior to the restore can hfspax prompt for each new part in the way that tar does? I wouldn't have the space to copy all the parts to my hard disk and cat them together prior to extraction.

I think so, yes. hfspax will prompt you for the new filename when appropriate.
Remember to type in the complete path, not just the filename, when hfspax ask your for the next filename. e.g.
filename:
full path:
or whatever place you prefer, obviously.

Resource forks do not appear to be restored with hfspax under Panther.
Running the latest available version of hfspax (hfspax1fc4.tar.gz) under Panther 10.3.9 I have had no luck retaining resource forks. I can see that hfspax attempts to back them up but on restore they are missing. I'll stick with xtar, which has not resulted in any problems. |
