232w ago - OK, do you remember the OLD PS3 Backup Tool? I've updated it, and now you can successfully write mixed backups on your PS3.
The new method mixes not all parts like before, but only half. Doing so, the PS3 recognizes the backup and restore, not only the "Integral" part, but even the part (50%) you added.
So the new formula is:
archive.dat + archive_XX.dat = INJECTOR
archive2.dat + archive2_XX.dat = DATA TO WRITE
You need the INJECTOR to begin the Write process. If you don't add Archive2.dat to your backup the PS3 writes the INJECTOR only. You need to create yourself the INJECTOR, in fact, it's unique for backups. If you have an old INJECTOR you can use it.
Here's a video demonstrating the process, with a guide below:
== HOW TO ==
1) Switch on your PS3
2) Go to Settings -> System Settings -> Backup
3) Connect a USB Drive or a Memory Stick to PS3
4) Select it in Backup utility
5) Make a Backup
6) Copy it to your Desktop
7) Delete backup from the USB Device or Memory Stick
8) Connect it to the PS3
9) Delete something in your PS3 (To make backup smaller)
10) Backup again and copy the 2nd backup to your desktop
11) Delete backup from the USB Device or Memory Stick
Now you have 2 different backups on your desktop.
1) Copy archive2.dat and archive2_00.dat from the bigger backup to the smaller one (see picture below).
2) Copy the Mixed (Bigger + Smaller) backup to a USB Drive or Memory Stick in:
(XXXXXXXXXXXX is the number of your backup)
3) Restore the Mixed backup from your PS3 (Go to Settings -> System Settings -> Backup -> Restore)
4) Once restore is complete, your PS3 has the files from the two Backup in HDD.
That means the PS3 writes files in the HDD, even if the backup is mixed with another. That can be useful in further hacking when you need to write a file in a directory, for example the Game directory.

I've noticed that for the most part, the archive.dat and archive_00.dat files both begin with an @ (If you view the files in a plaintext editor) And all of the other archive failes, (archive2.dat and archive2_00.dat in my case), all begin with a 0 (If you view the files in a plaintext editor)
Right now I am trying to see what would happen if you changed the folder names of the backups to dates that do not exist. Nothing unusual. I guess the PS3 doesn't care what the folder is named. Just to be sure I'm trying a few different cases. One where the folder name is as long is it can possibly be, one where the folder name is fairly short, one where the folder name is just a space, and one where the folder name is preceded with a dot (.)
All of them show up fine. All of them restore fine..
Trying to change the first character of the dat files. When all of the dat files begin with an @ symbol, the 800283F0 error appears. This could either mean that this is a catch all error code for corrupt PS3 backups, or perhaps it means that there are too many pointers, and not enough data files (With the assumption that archive.dat and archive_00.dat are files that contain pointers/references to the raw data and archive2.dat and archive2_00.dat are files that contain the raw data).
I dusted off my original 40gb harddisk that came with the PS3; and formatted it using the 2.80 update PUP. After this, I made a backup to my thumb drive. I downloaded semitope's backup, and overwrote my backup's "archive2_00.dat" and "archive2.dat" files with semitope's. I attempted to restore this new backup on my PS3 and received the following error: "The restore operation could not be completed. The system will restart. (800283F0)
After pressing the circle button, the PS3 restarts, and says "The hard disk's database will be rebuilt."
"Rebuilding database... Please do not turn of your PS3 System"
It restarts once more.
After it's done, nothing on my system has changed. It is still the plain vanilla formatted version. What am I doing wrong? Or does this prove that you cannot use other system's backups?
EDIT: I am fooling around with this a bit more. Now I am attempting restoring directly from semitope's backup.
EDIT2: Hmm, the system noticed me with: "This data was backed up from a different PS3..." Allowing it to continue anyways..
EDIT3: Rebuilding the HD database again and restarting.. I am now prompted with "Data for unregistered users was found on the hard disk and has been restored. The data has been restored for the users listed below. *User 1 *User2 *User3.
EDIT4: I believe this has allowed me to restore for the most part to semitope's backup. I see a game save for Bejeweled 2 for *User 1. Nothing for *User 2. Nothing for *User 3.
