Testimonial

"With their approach we are able to send just a fraction of the changed data and it finishes in just minutes."

How It Works

Bit-level Backup technology substantially reduces the amount of time it takes to perform an online backup of a large file.  While many services backup the entire large file every time, we are actually able to open the large file and extract just the changes since the last backup.

For example, consider the case where a critical database of customer records is updated daily.  Over time, this file will tend to grow large.  However, the amount of data added or deleted on any day may be just a few records.

With a traditional approach to backups, if even a single record in a file changes, a complete copy of the entire file must be transferred to the server.  This complete backup could take many hours to perform and result in substantial usage of offsite storage for each copy of the file maintained.
BitBackups are different.

When performing a Bit-level Backup, a complete file backup is performed the first time.  But, on subsequent backups, the software determines the records that have changed since the initial backup and transmits only the changed records (plus some administrative information) to the offsite storage server.

Since the size of the changed records is likely to be much smaller than the size of the entire file, a Bit-level Backup may take just a few minutes to complete.  In cases where multiple file copies are maintained, Bit-level Backup technology reduces the use of disk space on the offsite storage server.

Bit-level Backup technology makes extensive use of a local reference disk cache.  It also has built-in management intelligence to determine whether it is appropriate to transmit file changes, or to “roll forward” and perform a complete backup of a data file.

Databases, Outlook personal storage files (email), large documents and any other data files, which change only modestly each day, are ideal candidates for a BitBackup.

Offsite Data Backup Server
By enabling BitBackup for this database file, and permitting use of a local reference cache on the appliance, we are able to significantly reduce the amount of offsite storage and reduce the overall time required to perform backups on most nights (except roll forward refreshes.)
