Joomla website backup not restoring on my server using kickstart.php. Backup-file details are as follows- backup-file extension : .jpa, backup-file size : 980MB.
After clicking on "Start" button to restore backup, next error screen is as below:
It can be that your backup file is corrupted. I would suggest to try to restore the jpa archive in your local machine using Akeeba extract wizard, to get closer to a conclusion that the file can be restored or it is damaged. If it can not be restored locally, then there is a big chance that your archive is corrupted. Try to re-backup, but before you do so, also check what else directories apart of the joomla core ones are included in your backup, as it possible that you also include long logs files that might cause you issues restoring them, as you will read in the next lines.
Other possible issues why you can't restore it on your server are the time-outs, especially if your archive contains very big files (e.g. logs files as described above). You could try modifying the php.ini file and adjust the max_execution_time to higher value (e.g. > 120).
Another possibility could be that there are some permissions issues (??). What is the operating system of your server ?
