Cartika, a Canadian supplier management application hosting, issued a notice to users warning against the cloud based solely on the snapshots for backups. "Many cloud providers instant market as a sufficient backup solution, but snapshots of technologies, while useful for VM duplication or rollbacks are not a replacement for a dedicated backup tool," said Andrew Rouchotas CEO Cartika.
snapshots, which are a copy of a virtual machine byte by byte, are a form of backup, but snapshots, as expected by most cloud providers do not allow consider a number of data loss scenarios. A major drawback of instant regarding the handling of saved data, according to the CEO of Cartika, which often remains on the same server and storage physical volume as live VM. A failure of the sites supporting infrastructure and services of the organization will also damage the backup or make quick restores impossible.
"Snapshots do not include the file systems or databases, making it more difficult selective achievement data restoration and limits the portability of backup," added Rouchotas . "Moving instant between virtualization platforms is difficult, if not impossible."
managed hosting provider Cartika is the creator of the Bacula4Hosts backup tool company, a backup solution offering much more granular control of instant backup systems, including the ability to restore individual files, selected sets of files, databases and database tables, and mailboxes. Because they understand file systems rather than byte by byte copies, these backups can be restored directly to bare metal or any cloud platform.
