I have a virtualbox with host windows 8 and guest ubuntu 14. Now my disk space is running out and I'm reluctant to doing the complicated partition resizing which doesn't seem completely safe.
I've previously asked about resizing here https://askubuntu.com/questions/620051/how-can-i-resize-a-virtualbox-guest-os-ubuntu
Now it was mentioned that instead of resizing I could try a) cleaning up my system but that didn't help enough. I deleted files from an old installtion of altera quartus ii but it didn't free enough space.
What I need to do is import a large backup into mongo (> 2 GB that also needs some temporary space).
So I wonder if there is any way to mount a new partition from where I can import my large backup?
Any other advice what I can do but creating an entire new ubuntu image with larger space that is likely to consume all of my system space?
