There are a number of cloud storage appliances on the market that can be used as a backup target, including appliances from [[CTERA Networks]], [[StorSimple]] and [[TwinStrata]].<ref>Boles, Jeff.

Hybrid cloud backup is also beneficial for enterprise users who have security concerns. When storing data locally before sending it to the cloud, backup users can perform the necessary encryption operations, incl. technologies like:

Line 105 ⟶ 108:

Some vendors limit the number of versions of a file that can be kept in the system. Some services omit this restriction and provide an unlimited number of versions. Add-on features (plug-ins), like the ability to back up currently open or locked files, are usually charged as an extra, but some services provide this built in.

Most remote backup services reduce the amount of data to be sent over the wire by only backing up changed files.{{citation needed|date=April 2015}}<ref>{{Cite web |last=IT Manage Services |title=DATA BACKUP Services In Houston |url=https://itmanageservices.com/data-backup/}}</ref> This approach to backing up means that the customers total stored data is reduced. Reducing the amount of data sent and also stored can be further drastically reduced by only transmitting the changed data bits by binary or block level incremental backups. [[List of online backup services|Solutions]] that transmit only these changed binary data bits do not waste bandwidth by transmitting the same file data over and over again if only small amounts change.
