PSA 8.3 data-restore from prev. PSA8.x version?

    Hi all,

    I have a PSA8.0 backup, and during upgrade my server crashed.
    I have not reinstalled a new server with 8.3, and i have a backup-file from the previous server.

    I know this is not much information - but is there any problems having a backup file, from PSA8, and doing a restore on PSA8.3 ??

    Both the prev. server and the current one, is running Linux Debian.

    No the format of the backup is the same for all 8.x systems, you should be able to use a 8.0, or 8.1 backup on 8.3. Versions lower than 8.0 require you to run it through the conversion utility.

    I have just tried to create the mapfile using the 8.3 version - and i got this warning:

    WARNING: Backup file has wrong signature for this server

    Is that something that i need to take care of?

    Okay, now i have a BIG problem. I don't know what this means, as i have not worked with python at all.

    # ./pleskrestore --restore /root/daily_uxser01_backup -level server -map /root/mappen -verbose
    WARNING: Backup file has wrong signature for this server

    WARNING! Restore with "-level server" switch brings server to exactly the same

    same error here with a backup from 8.2.1 and attempting restore on 8.3.0:

    WARNING: Backup file has wrong signature for this server

    Returned this after spinning it's wheels for 10 minutes trying to create a map file.

    One new note, the "old" server was an Intel i386.
    This new server is AMD x86_64.

    I have verified that the content of the server is version 8.

    # ./pleskrestore -i /root/daily_uxser01_backup
    Backup information
    Dump version: 8.3.0
    File: /root/daily_uxser01_backup
    Type: Server
    Date: Jan 6, 2008 10:57 AM
    Size: 1.66 G

    How can i verify the backupfile itself, and check the content?

    Okay, now i have been able to extract all the data from the backup-file, into a simple directory.

    # ./backup-unpack extract -d /var/old-data /root/daily_uxser01_backup

    This tells me that the backup-file is OK, why can't i restore by using the pleskrestore application?

    Come on, anyone??

    Is there a problem with the Plesk Restore utility?
    - If so, how can i get all my 1.6GB Data into my server again? (without to much manual labour?)
