How to ignore but preserve certain large files?
Hi there,
I am using a parallels virtual machine. All valuable data is stored over the parallels network on Mac HD, that's fine. But there is a lot of stuff installed on the virtual drive which I don't want to get natively onto the Mac drive, therefore I would like to keep all uninteresting stuff on the virtual disk image. My problem is that Parallels has no read-only mode, so my disk images are changed every time they are mounted. That means several extra GB to be juggled around for every smart backup. Therefore, I would like to take one initial snapshot with SD, but then exclude the snapshot drom SD avtions, because it is such a waste of time. I'm wondering if this is possible. If I do a full backup the first time and then continue with smart backups, telling SD to ignore my Parallels images, would't the target be smart erased and I would loose my backup file, or is it so smart to always ignore certain files, also in the erasure phase? thanks - chris |
It isn't really possible, Chris, but you could store the Parallels images on a different partition. That way, you could back them up on a different schedule.
Alternatively, you could store their backups on a different partition, and back them up to that when needed... |
well I was afraid of this but thanks
Adding more partitions to my HD is exactly what I don't want.
When I'm done with all my testing and the final size of the disk image is sorted out, then an extra partition would make sense. In that case I would eventually prefer a bootcamp partition, but well, Parallels support is still limited, since you cannot boot while you have an external Windows drive attached... Anyway, saving stuff to a different location might work, despite the fact that I don't know how to avoid killing my existing file when restoring with SD from the backup - probably also not possible. But many thanks for your quick answer - Parallels are an order of magnitude slower :) |
hey would that work?
What about this idea:
If I run a shell script that shuts down my virtual before running SD and resets the file modification date to a certain value before running smart backup, would that work? Given that file size did not change, but then I would anyway want to copy. What exactly are you using as the copy criteria? Thanks a lot for your help - chris |
We're checking against all aspects of the file: size, attributes, dates, etc. It's going to be difficult to "fool" it. I think a bit of reorganization of where you're storing it is going to be a lot more effective...
