Hey,
I'm working in GIS field and I had the same problems.I find it very comfortable because my server is separated from guest os. So I can take the disk and work on any pc with virtual box installed (require admin right), and I have all GIS tools on the server, so the virtual machine is very self contained.
It is also easy to backup (but very slow due to huge iso file).

I use a USB2 okay-ish disk. Guest win XP 64 / win seven 32 ; Host Ubuntu 12.04 32b.
About perfo : I do complex queries. Perf are OK for my use case (about same as a dedicated XP 32bit).

It appears you are looking to take the PostgreSQL data directory from machine to machine on an external drive. I fear you will run into some potential problems:On 09/10/2014 02:00 PM, Daniel Begin wrote:First, I am a Newbie regarding PostgreSQL …
I just started to look at PostgreSQL to implement a large GIS DB (1Tb). The data must reside in an external disk with eSATA connection and may be moved to different locations (and Windows desktops/laptops). I was looking to install PostgreSQL and PostGIS extensions on each PC (setting-up the proper PGDATA directory to the external disk) until I read about PostgreSQL and PgAdmin Portable …
http://sourceforge.net/projects/pgadminportable/
http://sourceforge.net/projects/postgresqlportable/
Is that a viable alternative considering the expected size of the DB? Any comments or proposal would be appreciated J

1. Performance (mentioned by others).
2. OS mismatch. Have you ensured that all client machines are running identical setups? The underlying files are not guaranteed portable between OS versions and 64/32-bit. In fact they probably won't be.
3. Backups. What happens when one user screws up the database?
Perhaps you could explain further the genesis of this requirement. The message list is littered with questions like this asking how to implement a certain solution when, given an understanding of the reason the question is being asked, a far better solution exists. This happens even more often when the person asking is a "newbie."
Cheers,
Steve
