Updating and backing up an image file   29 December 2018, 16:30

Dear Support,

Yesterday I had a system crash and now some files in the RAM disk are in an old state or missing completely. So I have some questions regarding a RAM disk image file:
  • if I do an unmount, will the content of the image file be deleted or is the content still there when I mount it again?
  • how can I mount a backed up image file?

Thank you in advance for your support.
Kind regards
Erich

If you unmount the image file, nothing will be changed in it unless you have the Save Contents to Image option enabled. If that option is checked, any changes you made will be written to the image upon unmounting.

To access a backed up image, choose Image - Mount Image from the main menu and select your image file. Then you can copy data from and to that image via a drive letter. Once finished working with the image, unmount it via menu Image - Unmount Image.

Thank you so much for the quick answer. I have one more question:
  • If I use the Save button to update the original image file, is it possible to copy the image file to another drive while the image file is in use, and will I have the updated state in the copy? Or do I have to unmount and then copy the image file?

Technically, you can copy a mounted image file: the file is not locked for exclusive access.

However, it is worth noting that the image is a random access file, while the copy operation is sequential. This means that if writing to the image coincides with copying it at the same moment in time, the copied file will likely be corrupted. Otherwise, it should be Ok to copy a mounted image file if there is no writing being done to it at that moment.
