C
Checkpoint file
A file that accompanies an Exchange transaction log (p. 57) stream and tracks how far Exchange has
progressed in writing logged information to the database file.
Circular logging
A Microsoft Exchange Server logging mode. In this mode, Exchange overwrites and reuses the
transaction log files (p. 57) rather than creating new log files.
Continuous Data Protection (CDP)
Continuous Data Protection (CDP) allows reverting the protected data to any point in time.
In Acronis Backup, CDP is a backup scheme applicable to Microsoft Exchange information stores (p.
56), storage groups (p. 57), and databases (p. 55). In this scheme, you specify when to perform full
backups. In addition, the transaction log files (p. 57) are backed up automatically as soon as they are
closed by Exchange. Having both full backups and transaction log backups (p. 57), you can select any
point in time to revert the Exchange data to.
Copy-only backup
Creating a full backup of a Microsoft Exchange information store (p. 56), storage group (p. 57), or
database (p. 55) without truncating (p. 57) the transaction log files (p. 57). Use this backup method to
obtain a full backup without disturbing continuous backup plans. For example, if a database is
protected with CDP (p. 55), you can do a copy-only backup of the database for transportation to an
off-site location, testing, analysis or other purposes.
Copy-only backup and express full backup (p. 56) are mutually exclusive. You can select only one of
these methods when creating a backup plan.
D
Database-level backup
A backup that contains Exchange databases (p. 55) and Exchange-related information from Active
Directory. When performing backup at a database level, Acronis Backup backs up database files,
transaction log files (p. 57) and other associated files at a file level from a snapshot taken using
Volume Shadow Copy Service (VSS). The Exchange server structure, cluster structure, user accounts
and user's settings are extracted from Active Directory.
The main purpose of this backup type is disaster recovery of Exchange. You can also recover
mailboxes, folders, e-mails, contacts, tasks, notes and other items directly from database backups.
