In April 2003, readers of the amanda-user mailing list were asked
fill out and submit a survey form describing their use of the
amanda backup system.  Seventy two (72) responses were received.

What follows is a summarization of the responses describing the
organizations using amanda.

[Surveyor's Note]  The `Categories' were my grouping, they were not on the 
survey.
I expected more in the SOHO category.

[Surveyor's Note]  Extent of amanda usage was asked on the survey.  Few 
indicated
that their entire firm based their backups on amanda, and then only relatively
small companies (like JG Computing :).  Thus the category is `University 
Department'
not `University'.  Similarly, amanda is used by a groups within organizations 
like
the chemical manufacturer or computer manufacturer or federal government noted 
above,
not the entire entity.  But amanda may have helped produce the tires you are 
riding
on, the workstation you are typing on, or to collect the taxes you pay :))

[Surveyor's Note]  The totals are greater than number of submitted surveys
as some respondents described multi-national installations.

[Surveyor's Note]  Americans must be procrastinators.  For a while, the
number of non-US submitted surveys exceeded the ones from the US.
