FBackup

not enough info
what kind of privilages does it need to install

if it needs admin priv. than it may not work as you will want it to or dev's won't do it because of the admin priv. needed

we need to know if it is freeware and what kind of license it uses

i mean it is easy to find out but it is faster to have info provided

give more info and maybe a dev will see what can be done

i may even try my own way of making it portable

it needs admin privilages to install i just checked

i will still try tho but a official dev may not
