Eye balling his parse disk size
on Jul 22, 2013 at 5:31:10 am

Hallo,

After some in depth research, I really like the idea of creating a sparse disk image to store my media, events and projects in.
My question is: if I'm importing the media into the event folder, is there a rule of thumb, how big I should make my sparse image, in relation to my source material, to be sure to have created a big enough partition. In FCP7 I had a good feeling on big a project would get, based on knowing how much source footage I had. In X, I wouldn't have the slightest clue.


Greetings,

I think you might find this thread very helpful:

We have been using the free CreateDiskImage utility from Andreas Kiel on many FCPX projects now without any problems. It makes it very easy to create sparse images and bundles, and to adapt them if needed: http://www.spherico.de/filmtools/createDiskImage/

If you use a backup system that does incremental backups (Time Machine, CCC...) you should use sparse bundle disk images instead of sparse disk images. Will save you a lot of time during backups.

I've read that bundles are better for other reasons. They might get corrupted in a small chunk rather than the entire image going down. And they are faster to down-size if the need arrives.

But (and I've asked this in another post), some end users are reporting that their sparse images are slower than the drives they are in and a call to Apple Care pro app department got me a strong recommendation not to use sparse images - that they would slow things down. My tests on a raid with plenty of overhead and relatively small images housed in it did not show this however. I used Black Magic and AJA apps to test the speed of the raid and the sparse image. If anything the images were faster.

Sascha,

As said you should use sparse bundles. They make backups easier and what is more important the reconstruct after a corruption easier. Remember a disk image is just a file!!

About the size: You should somehow know what amount of media space is needed for a complete project. Add 200 MB for each event and each project version you plan.
Once you reach the limit of the virtual disk you can resize the sparse bundle. But you have to quit FCPX and unmount the virtual disks. The limit of size is limited to the free space you got on the volume the sparse bundle resides on.

My free http://www.spherico.com/filmtools/createDiskImage
and http://www.spherico.com/filmtools/X-Files/index.html
can help a lot to handle it easily.

I've been using Sparse Images instead of Sparse Bundle Images because I didn't know what the difference was. Is there any way to convert them to Sparse Bundle Images?

"... Is there any way to convert them to Sparse Bundle Images?"

Good question -- I don't know. But I will do some research.

Why not make an empty sparse bundle image and clone the sparse image to it? Any reason that would not work?

Craig's idea is the most obvious one -- and at this moment the easiest one

I said "Good question -- I don't know." cause I first thought you can do it with Disk Utility -> Convert. But that doesn't work.
You can do it in Terminal with a command line, but that's probably nothing an editor loves.

I will implement this feature to the next version of X-Files Pro next week.

Just for the records -- it's implemented now.
