I was having a chat last night at the counting house and rememebred something I was fiddling around with a few months ago but never got sorted.<br>I have a Windows Mobile based phone. I have 2x 2GB SD cards. I have an SD card reader on my laptop. I have
1.4GB mini DVD-Rs<br>Basically, I was wondering if there was any way to back up the SD cards into a single file archive, but with no compression. I never use more than 1.4GB on any card, but would like to have more than 2 options, say 1 for music, one with photos, one with graphics applications, one with emulators and roms etc. In the end I would like to automate it so I can switch the contents of the cards, with a shell script for example. I was kinda hoping dd would give me an option to only copy until the partition went blank.
<br>The reason for me not wanting any compression is mainly the photos, the camera on it is crap, but of some use anyway, however if I keep compressing and uncompressing over and over again, I'm eventually going to end up with every file being one large pixel.
<br><br><br>On a similar note, is it possible to create a filesystem within a file and mount it with -o loop but not have to set the file size before. I have managed to create a 4GB ext3 file but was wondering whether it would be possible to have one with a variable size, the more you put in it, the bigger it got kinda thing.
<br><br>Thanks in advance<br>Nistur<br>
