Microsoft supports different types of backups for their Exchange Servers. They can be categorized into two major types; online and offline backups. Both of these categories have several subcategories, which are mentioned below:
When Microsoft Exchange backups are performed while the exchange services are running, the backup is called an online backup. The biggest benefit of online backups is that, you don’t have to stop any of the services of the Exchange Server to perform this backup. But, the files that are being used by the running services will be skipped in the backup.
You can use a combination of the Exchange Agent or Exchange-aware, and CloudBacko, to perform online backups of your Microsoft Exchange Servers. There are four different types of online backups available for Exchange Server database.
- Full Backup: In a full backup, the whole directory or exchange store will be backed up; including the log files. This backup marks the backed up elements so incremental and differential backups can be performed later.
- Copy: A copy backup is similar to the full backup with one exception- no objects are marked when they are backed up.
- Incremental: Incremental backup lets you backup subsets of objects that have changed since the last full backup. To back up from incremental backup, you need the incremental backup and a normal backup.
- Differential: This type of backup is used to backup the changes in the directory that have happened since the last full backup. A normal backup and differential backup are required to restore data from differential backups
Offline backups are backups of Exchange Servers, which are performed when there are no exchange services running. This allows the backup software, like CloudBacko, to have access to the entire database. There are two different types of offline exchange backups:
Planned Backups: These backups are performed after properly shutting down all of the exchange services. Planned backups result in consistent and reliable backups.
Unplanned Backups: Unplanned backups become necessary when your Microsoft Exchange Server fails. If a failure occurs, this is the only option you are left with.
You can use CloudBacko, to perform all of the Exchange Server backups mentioned above. With the use of this backup software, the process will be simplified and your data will be more secure.
