need tto update backup if there is old backup in memorycard
I have old backup(from the previous backup system) in the memory card. There is also one created with the new backup system. It forced me to update the backup before I can restore from that new style backup. The update backup created new sailfish_backup_*.tar file with that old date from the old backup system. I did not lose anything but it was very confusing to first select one from very old backups.
