File-level backup allows backing up files and folders from the CTERA Agent local interface
to the appliance. The CTERA Agent can back up both unlocked and locked files.
In addition, you can back up the following server applications:
Microsoft SQL Server
Microsoft Exchange
Microsoft Active Directory
The backed up files and applications can later be restored as needed.
Disk-level backup
Disk-level backup, also known as “bare-metal backup”, allows backing up an image of the
CTERA Agent-installed computer’s hard drives to the appliance. In case of an operating
system error or a hard drive failure, the computer can be restored in full from the
disk-level backup, returning the system to its exact state when the backup was
performed. You can also restore disk-level backups to dissimilar hardware (provided it has
sufficient disk space), and even to a virtual machine (VM).
When CTERA Agent is used in conjunction with CTERA’s Cloud Backup, a copy of disk-level
backups is stored offsite for complete disaster protection, while maintaining a local copy
for fast restore. CTERA’s advanced deduplication efficiently handles the disk-level
backups, ensuring that only differences are sent over the Internet.
When CTERA Agent is used in conjunction with CTERA’s NEXT3 snapshots, users can easily
roll back to earlier versions of their disk-level images. NEXT3 ensures that only differences
are stored between versions, thus greatly reducing the required storage space.
In Windows Server 2003, disk-level backups are stored in NTBACKUP format. In all other
operating systems, disk-level backups are stored using the industry-standard Virtual Hard
Disk (VHD) file format. VHD files can be mounted using standard tools to allow extraction
of individual files and folders, and it is even possible to run the VHD disk image on a
virtual machine (VM) for immediate disaster recovery after hardware failures. For
information on restoring files from disk-level backup, see Restoring Files from Disk-Level
Backup.
