Re: [BackupPC-users] Archiving
2008-12-28 13:47:37
I use BackupPC_tarcreate and pull the backup off. These can be 12-15GB. I then run this through rar and set a chunk size of 50MB. These usually compress down to 6-7GB of 50MB RAR files. I then par2 them to fill the remaining space in the media I'm using just to be safe. I just did a little script-fu with dialog to make a wizard for this process. RAR files are readable on any major OS as well as par2 tools like quickpar. The tar file is readable in 7zip, winrar, cnu tar, etc etc.
On some archives I also use a fuse program archivemount to mount up the tar archive and then delete files out in case some extra directory copies were leff handing around. It really just creates a batch of things to do after unmounting but it is more convinient than extracting the archive, then archiving it up again.

Sorry, I deleted the original message...
My suggestion would be to modify the various settings in config.pl and
use mkisofs or similar to create a DVD iso image. Then later use
cdrecord or similar to burn that to the DVD. Thus, any OS/system could
simply/easily read the contents.
Some challenges that you may need to resolve:
1) What happens when your archive exceeds 4.7G or 9G or whatever
blueray size, etc...
2) What happens when filesize or filename/path length is too long for
ISO ?
3) How to seperate the individual machines you are backing up ?
Perhaps one client machine for disc, or multiple on one disc etc...
This is one of those cases where we can provide some hints, options,
but at the end of the day you will need to determine what is the best
solution for you.... Possibly, if you provide enough information, then
we may be able to provide better options/suggestions.

Adam
