I don't believe rdiff-backup is able to do this on its own; rdiff-backup suits a situation in which you want to backup data (not whole system) and to do so repeatedly (e.g. day after day), and be able to recover data from earlier backups as well as from the latest one. Even if rdiff-backup can backup your whole system it cannot easily restore it. To restore a system you need to be able to boot up in a temporary OS, do the partitioning and formatting of the (new) system disk etc etc (and then copy all the system files and data), rdiff-backup is not designed to do this.

I want to backup a whole linux system to windows for restoring the system from windows to linux later.
I successfully installed native rdiff-backup on windows xp and it can backup linux data to windows folder.
But it seems failed if there is symlink in the linux system. Error information attached at the end.
I want to know:
1. I want to backup all the information of the linux system to windows and so i can restore the OS(not only data) to linux later. I think the information includes user/group/permission etc. At first i want to use rsync to do so but found rsync can not do it. and I found that rdiff-backup will use meta-data to keep such information, so I assume it can do so. correct me if I am wrong.
2. If i can get what I need with rdiff-backup, what should I do?
If you want to backup a whole linux system for easy restoring, then I suggest you look at a package designed for this purpose. I use mondo http://www.mondorescue.org - and it doesn't need Windows. You can create a backup on a flash drive, take this to a different machine, boot it and restore your old system to the new hardware. It offers differential backups, but not the 'history' magic that is rdiff-backup's special trick.
I suggest you use both: mondo to backup your system (excluding your own data files, because these may be too big for a flash disk), and then rdiff-backup [over a network to another machine] for your data files. mondo only needs to be run occasionally, rdiff-backup you should run frequently (e.g. as daily cron job). When disaster strikes, use mondo to recover your system and then rdiff-backup to recover your data. And of course if you need the data from one week or one month or even one year ago, rdiff-backup will oblige.
thanks for your reply.
I have a solution to recover from disaster which can restore the system to factory default. After that, I want to restore the system to latest or earlier version. I can achieve it in linux <-> linux way. I can back up the whole system to a Linux host and then restore later. It works. But came to Windows, problems happened.
As the linux system I am working for is a mobile device, and users need to backup the device to a host machine, which usually is a windows machine. So I am seeking a solution to backup the linux system to windows.
If there are only data files, it is relatively easy, there are many solutions for it. but I want to design the feature similar with Apple's Time Machine. I want to restore the system to earlier state, not only the data, but also application/application config etc.
So I need to backup/restore the whole Linux system files to/from Windows system.
