Root NAND backup question

[RAFdude]

Each time a ClockworkMod backup is made does it overwrite the previous backup or give an option to restore from? Thanks in advance

Although I do not use Clockwork, I know it will not overwrite previous backups. Be careful making too many backups, however, because they take up a lot of space on your SD card.

CW creates a separate backup each time you create one, organized by date.

I assume that you restore a nand backup differently with CW than the process for flashing a ROM? I noticed the ROMS I downloaded are zip files and the NAND I have is not.

Sorry, noob question but I figure it fits the thread.

Flashable zip files are basically packages that include whatever files the developer wishes to replace along with a script. That script tells recovery what to do with those files. Those files can be every from all system and boot files (basically, a ROM) to just a few framework files (mods, themes, etc.). Really, it's just a method of modifying or replacing an existing system.

A nandroid backup is completely different. It is taking a snapshot of your system exactly the way it is. That includes all partitions including all system and boot files, but also data, etc. These files are in a certain format. Recovery will not discern what files to replace, etc. like a flashable zip. There is no script. These files are strictly image files that recovery uses to replaces entire partitions. Therefore, when you restore a backup, you're replacing everything that was done since the backup. Always remember, flashable zips and nandroid backups are completely different. To restore a nandroid backup, use the restore option. Do not attempt to search for it via the install/flash zip menu.
