Description of Types of Backups
Type of Backup Description
Full
Backup
|
For
server backups, this schedule type will back up the Exchange Server
|
database
and associated transaction logs. All committed transaction logs
|
|
will
be truncated (deleted) after they are successfully backed up.
|
|
For
mailbox backups, this schedule type will back up the entire mailbox,
|
|
including
all the folders and messages in that mailbox.
|
|
For
the Public Store, this schedule type will backup the entire Public Store,
|
|
including
all the folders and messages within the Public Store.
|
|
Differential-
|
A
differential incremental backup will only back up changes since the last
|
incremental
backup
|
full
or differential incremental backup. Differential incremental backups can
|
be
performed of databases, the KMS and SRS services, mailboxes and of the
|
|
Public
Share.
|
|
When
using this method to back up a database, only transaction logs are
|
|
backed
up. After the successful backup of the transaction logs, all
|
|
committed
logs will be truncated (deleted). The truncation of the transaction
|
|
logs
sets the context for the next backup.
|
|
To
perform a full restore the data needed is contained in multiple
|
|
NetBackup
images. One image for the full backup and another image for
|
|
each
differential incremental that was performed.
|
|
User
Backup
|
A
user backup is not automatically scheduled and is initiated on the target
|
client
machine.
|
|
A
user-directed backup of a database is identical to a full backup except that
|
|
the
transaction logs are not truncated. Because of this, user backups are like
|
|
taking
a snapshot of the databases at a given point in time without
|
|
impacting
the content of ongoing full and incremental backups.
|
|
You
may want to consider creating a separate policy for User Backup
|
|
schedule
types. This will allow you to easily separate user-directed and
|
|
scheduled
backups when restoring files. If you decide to create separate
|
|
policies
for User Backup schedule types, the considerations are similar to
|
|
those
for automatic backups. A Backup Selections list is not needed because
|
|
users
select the files before starting the operation.

A full backup should be good. There should be an option
to do a full backup with a purge of the log files vs a full backup copy without
the purge of the log files.
