How to backup project files?

I always load my clip from my camera to a external hard drive, via FCPX.

The project files are stored on my computer´s hard drive. I want to backup it, and put it on my hard drives.
Can I just click and drag the folders from my internal hard drive to my externals?

Since FCPX are saving my work after every move, can it save it on both my internal and external, or do I have to do the backup on my own?

Don't copy in the Finder, you'll end up with duplicates that share the same database ID, and FCP X will open which ever one it finds first, and ignore the other, meaning the backup may open, the working copy may not. That said...

If you manually copy over, do it inside FCP X, so it can assign unique IDs.

If you're only worried about the database files, get Pro Versioner from Digital Rebellion. It will backup the project files like Motion's Autosave function does, at specified intervals.

If you want full backups, get Carbon Copy Cloner and have it backup nightly, or manually. I've posted a guide about CCC for FCPX users that Mike Bomich has approved. This can backup your whole drive, avoiding the multiple event/project confusion, or only backup the FCPX specific stuff.

Some combination of these will keep you safe. It depends on what your specific needs are.

I copy/backup to a Synology NAS, and don't have the problem as FCPX can't see the disc-format on the NAS. So using a NAS can be away around the database ID "problem".

Just before Ben answered, I went to "Project Properties" and duplicated the project. I then got to choose where I wanted to duplicate. I chose a different hard drive.
Isn´t this a way to do it?

As for my events, I made a copy inside FCPX.

NAS works, too. There are many ways to do backups. Depends on how much money you want to spend.

That works, also. There is no right or wrong way, only the way that works for you. I prefer using CCC with a dedicated backup drive, and automating the process. If I had a need for NAS, I'd spend the money on it. But local backup drives are cheaper for me, personally, in my specific situation.

I used to have a fibre RAID and Final Cut Server that I worked with. But my business over the years has changed, I don't need the massive RAID any longer. So I've been fortunate to be able to simplify my setup (as per my article about CCC and FCPX).

Your unique situation will determine what works for you. Local automated backups, NAS, Pro Versioner, CCC, fibre channel, CatDV, USB/FW/T'bolt, dozens of ways to do it.

Just have to determine what are your specific needs, what is your budget?

1- Are you looking for an inexpensive way to only backup the "CurrentVersion" files for Events and Projects? There are two options. "Backup For Final Cut Pro X" (new, I've never tried it out) and "Pro Versioner" (which has been around a long time from a reputable developer).

2- Are you looking for a dedicated backup for full Events & Projects plus the media, etc? There is CCC on either local drives or NAS (professional level, flexible backup) or TimeMachine on either local or networked drives (hobbiest level backup).

We won't even go into offsite, cloud, and the other flavors available.

So, for this discussion, as per 1 & 2 above, which do you need, or do you want both? In the case of (not "if" but "when") a total disaster and a drive crashes and loses everything 100%, what on that drive is vital, or not?
