# dm

dm is an acronym for the D3 data manager account which
contains the files necessary for basic system operation.

D3 makes extensive use of its own data management capabilities
to manage system-related data in the dm account.

There are three
files on the dm account that are used by the system and the users.
These files are tcl-stack, users, and pibs and should be copied using
the t-dump command prior to performing an operating
system upgrade. After a full restore, these files should be loaded
using the t-load command.
