Mis-saves happen. It is a fact of the computing world. The ‘Intelligent’ recognise the fact and provide for it. Cloud service vendors live with this reality and understand its implications. They consequently, take extraordinary efforts to ensure that mis-saves do not cause data loss for their customers.
Most cloud vendors use versioning and time stamps to distinguish between backups and protect customer data against mis-saves.
Each file that is saved into the system is tagged with a unique identifier and a time stamp. The original or the first copy of the file that is saved into the system, is called the primary file and any copies of the file saved from the same node or different nodes are identified as replicas of the original. These copies are then deleted and only one copy of the file is retained.
If changes are made to the file and it is saved into the repository, the new version of the file is compared with the existing version of the file and it is tagged as a new version with a version identifier. The backup algorithm identifies changes in the file and saves the changes to the file as a new version with references to unchanged content in the original file. Users, however, will be able to see all the content in the file version called, as data from the original file replaces the referenced sections of the file when the file is being displayed.
It follows that mis-saved files will not result in complete loss of data. Only the changes made to the new file will be lost and users can recall the original version of the file from the backup repository and redo the changes required once more. They can even use the latest version of the file that is available on the system to rebuild the lost version of the file since most cloud vendors permit users save and retain many versions of a file in the backup repository.
We, at Backup Technology, are powered by Asigra, a robust agentless cloud backup system. Our continuous backup system in place constantly monitors changes to files and saves the changed file as a new version of the file. Since new versions are created after extracting the changes and creating pointers to unchanged content—the new versions occupy less disk space and are smaller in size. Users can access versions of a single file from the storage. Additionally, the open file driver that comes with our software automatically backs up files that have been left open for long periods of time in applications such as Outlook, QuickBooks and Simply Accounting. It performs backup snapshots of data as scheduled back on to servers. So, we invite you to try our software and experience first-hand the power of always having your files saved for you automatically and constantly without conscious effort on your part!
