Problem restore backup

[offboard]

I am unable to restore my backup tried all versions of xampp and unsuccessful

then to prove that the problem is xampp installed the latest version and did a backup :

Code: Select all

sudo /opt/lampp/xampp backup
alien backup # sh /opt/lampp/backup/xampp-backup-07-07-15.sh
/opt/lampp/backup/xampp-backup-07-07-15.sh: 58: /opt/lampp/backup/xampp-backup-07-07-15.sh: function: not found
egrep: md5sums: No such file or directory
^C
alien backup # bash /opt/lampp/backup/xampp-backup-07-07-15.sh
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

cat: VERSION: No such file or directory
Installed:   XAMPP 5.6.8-0
Backup from: XAMPP
The backup sofware is not able to handle different XAMPP versions.
Your backuped configuration from  may not work with 5.6.8-0 and may need manually corrections.
XAMPP: Do you want to continue [nein] y
Let's try...
Restoring MySQL databases...
/opt/lampp/backup/xampp-backup-07-07-15.sh: line 184: *.sql: No such file or directory
* FAILED: cat: output: No such file or directory
Restoring MySQL user databases...
/opt/lampp/backup/xampp-backup-07-07-15.sh: line 193: mysql.sql: No such file or directory
MySQL user FAILED: cat: output: No such file or directory
Backup complete. Have fun!
You may need to restart XAMPP to complete the restore.

##BACKUPDATA##

is there any possibility to extract the files manually?

I already had a similar thread a couple of weeks ago, Xampp backup does not work correctly (as stated in the readme!!), i found out, that the skip command (skip=203) is wrongly calculated. It must be 206 or more (i do not remember exactly). This leads to falls data.

The main problem is, that the baclup file is a mix of text (shell script in the beginning) and followed by binary data. If you have sufficient linux skills, you can split the backup file into the shell part (this is not needed) and the binary part, if you edit the backup file, you will see a line which indicates where the binary part starts. You can split that file with the head or tail command with the proper offset (i.e. that is how it is designed to run, but 203 is the wrong number).

If you succeed to store the binary part into a separate file, this file is a gzipped tar file. You can unzip it, then untar it, this results in many other files (you will see, what these files are meant for). I succeeded to do so for another user, but in the moment i am not at home cannot help you on that issue any further.

I could recover my data successfully !
I opened the file backup ... sh with vim editor and deleted all up to ##backupdata## and then rename it to data.tar.gz and managed to extract all files.
