Hi,

We are planning to setup a media server in one of our remote office and try to use media server deduplication option. Is it possible to configure USB external HDD as a nebackup storage unit and select pure disk as disk type?

Not a good idea.

Please review 'Table 3-1 Deduplication storage requirements' in NBU Dedupe Admin Guide:  http://www.symantec.com/docs/DOC5187

I doubt that USB disk will satisfy required read or write speed.

You should also use a disk subsystem that prevent loss of data in case of single disk failures (RAID). Since dedupe is highly random write/read some caching will improve performance.
