Hello guys
Just checking for any new news regarding this problem of mine,
Thank you
i tried and reset the server and made a fresh install ( after a lot of work due to easy install didnot work for me and used the manual part that took me a while to get everything in correct place ) and tried again with dropbox backup but still does not upload private files or files to dropbox, only database
i tried manual backup and it worked, it sent me an email with a link to database, private files folder and files folder and i downloaded them manually

My problem is fixed, and this is how i fixed it,
I checked perl locals settings and found out that there is no arabic local ar-utf-8 setting in iy, i added it to the en-utf-8 and tried backup again, and it worked for all files
Thanks guys, but did not think that the solution would be that simple 
Hope it would help other guys if they face same error but with other languages
i used this lilnk to change perl locals so thought i would help other people on how to do it
Good to hear you fixed your problem, thanks for your update.
