Hi,

I am looking for some utilities to backup to Fedora with restore point(just like in windows). I like to backup every week and restore it to earlier version if some upgrade/installation goes wrong.

I had insalled from RPM having a tool with GUI- CloneZilla , BackInTime,LuckyBackup . All these tools were able to backup only USER data , not the OS. If I select the root directory to backup, it was failing with error as permission denied. I have given full access to Backup destination folder, still didnot work. I guess, I need give Unlimited access to those tools and dont know how. Please suggest the way

Also, am running Fedora from external hard drive in some partition. Trying to export it to another partition in the same Hard drive.

That is probably the most difficult way to back up. IMO you should back up your data in HOME, any shared data such as is used by servers (apache) if you have it, and a copy of any system files you edited.

This makes for smaller more reliable backups.

Be warned that simply making an image with clonezilla or similar is not a backup as you need to restore boot and restore your partitions.

@bodhi.zazen Thanks , I didnt know abt dnf ..

If I create Fedora OS image using clonezilla which is running in an external hard disk, can reuse same image run in another external hard drive ? . Also extracting that image file in another hard drive which might create actual partition as in the first hard disk ?

You can boot the image file (with KVM) yes, but, to put it onto another hard drive is another matter. Your /etc/fstab and initramfs need to point to the proper location so it requires manual intervention.

The fstab generally doesn't need updating because it uses the UUIDs of the filesystems instead of partition names.

If he puts the cloned image onto a second HD it will have the same UUID and the system can have problems consistently booting the correct installation if both HD are connected at the same time. Also we really do not know if the OP is using a boot partition, LVM, cyrpt, etc. My advice would be to change the UUID and update the system files.
