LuckyBackup not working in LL50

[Şerban S.]

[...] Like your regular user for backing up your /home folder it woks fine but if you want to backup the whole system you need to run it as root/superuser as it's not working. It's a bug.

I never use it to backup /home or / (Root). It's a waste of time and space. I use CloneZilla. I only backup with LuckyBackup my personal data, nothing else.
So, I never use the "As Root" version. I only used it once, to backup Home (it's a partition) and I was sorry. It took ages (some 15 minutes or more) and sucked me 7 GB of HDD space. Bad business! :o
A common CloneZilla backup, takes below 3 GB. Some 2,5 GB / 7GB data.
LuckyBackup is very handy for 1:1 backup tasks, since you can access files directly. And is fast enough for this kind of job.
(Actually, the Oscar goes to rsync, but...)

PS:
A bug? What bug?
rsync works in real time so NEVER backup the whole system, since it leads to many errors, due to system locked files. I thought you knew this. That's the second reason I never tried to backup the system with LuckyBackup. Too many files are changing too fast and this prevents rsync to do its job, whatever superuser you might be.
These are basic backup rules: never backup a running OS. Do it from a bootable backup tool. If you ever used TimeShift, I bet you noticed it works after shutting down the system and re-loading from RAM.
There is a difference between being a root user and trying to copy a common file and copying a system locked file. You need to issue a special command to unlock the file, which will then conflict with systemd, for one.
You may do as you please, it's your choice, but this is how it works. It has nothing to do with me, or you or anyone else. It is just the way the OS operates.

Best regards!
