System Administrator’s Guide to Installing DataMgr
3-6 Setup Tasks
Back Up
Databases
To effectively and efficiently manage your clients’ file systems,
coordinate the execution of the following utilities by scheduling
them as cron jobs:
•
/etc/dmfs/user/utils/dmfsscan — controls file
migration.
•/
etc/bfs/usr/utils/bfsmaint — copies and
replicates migrated files according to the defined storage
policy as well as manages the retention and expiration of
migrated files.
ADIC recommends that you schedule these administrative tasks
after the backup of a client’s managed file systems has
completed. Therefore, the sequence of execution should be as
follows:
Step 1. Back up the DMFS client managed file system with
the DataMgr
dmmode command and one of the
following:
• A third-party backup package.
• Or, the UNIX tar or cpio command.
Step 2. Edit, if needed, a
cron job to back up the BFS
Database with
/etc/bfs/usr/utils/bfsdb_backup. For days
and times, see “Schedule cron Jobs” on page 3-4.
While the BFS database is being backed up, the
database is locked to prevent any modifications to the
database until the backup is complete. Successful
backups are sent to
/etc/dm/raima/log/
bfsdb_backup.completed.
