What are the 4 types of exchange backups?

Answer Posted / suresh.rajaram

Normal (or Full) The normal backup process backs up the
directory or Exchange store in its entirety, as well as the
log files. To restore from a normal backup, only one normal
backup is needed. A normal backup marks the objects it has
backed up so that incremental and differential backups have
context. This is accomplished by backing up the entire
database and all the log files, and then purging the log
files.

Copy The copy backup is the same as a normal backup
except no marking takes place to give incremental and
differential context. This means that performing an
incremental backup after a copy backup is equivalent to
performing it before a copy backup. Use a copy backup to
get a full backup of the directory or Exchange store
without disturbing the state of ongoing incremental or
differential backups.

Incremental An incremental backup backs up the subset of
the component that has changed since the last normal or
incremental backup. Then it marks these objects as backed
up. To restore from incremental backups, each incremental
backup since the last normal backup and the normal backup
are needed. An incremental backup backs up only the log
files, and then purges them.

Differential A differential backup backs up changes in
the directory or Exchange store that have occurred since
the last normal backup. To restore from differential
backups, one differential backup and one normal backup is
required. A differential backup backs up only the log files
but does not purge them.
