Raffle: Oops!Backup – ReverseDelta and laptop backups
By Michael Pietroforte | No Comments | PermalinkIn my previous post, I described Oops!Backup’s CDP features and its advantages over conventional backup tools. Today, I will give you an overview of the tool’s so-called ReverseDelta technology and how you can use the tool for notebook backups.
Oops!Backup’s ReverseDelta stores file changes in so-called delta files. These delta files contain changes at the byte level. There is some overhead if only a few bytes are changed, but this can save a lot disk space on your backup drive if you have to secure large files as they are common with database systems. For instance, a conventional backup system will store a full 10GB database if only one record has been changed, but Oops’Backup would only require a few MBs of additional space. The tool allows you to configure the file size on which ReverseDelta is invoked, and you can also specify the number of versions after which a full copy of a file is preserved.
