Because a backup is not enough, the continuity of data in cold storage

19/09/2018

A cold backup or cold backup is one that is carried out offline and during which the data is inaccessible to be updated. This is the safest way to perform a backup because it avoids the risk of data being copied by third parties. However, it implies a downtime because users can not access the data during it.

A cold backup can be done on another disk in the same server where the data is located but if the server is blocked, so will the backup. To prevent and avoid this situation, discs are often copied to another server that might well be Glyphstock.

Cold backups can not be interrupted by a virus or suffer intrusions and are immune to power surges or power cuts. They also prevent data from being overwritten or deleted.

Cold backup vs. hot backup

A cold backup is a secure backup, without unforeseen circumstances, but it can not be used directly in systems that require 24/7 operation because there can not be logged-in users and the system can not register any activity to ensure that the data does not change during the backup and that the files remain unchanged when the system returns to operation, when it returns to normal. It is necessary to take a copy of the data and from that copy make the backup.

The servers used for the cold backup will remain off until the next backup or they could also be used if there was a disaster and it was necessary to enter disaster recovery mode. That's when Glyphstock makes more sense for companies because, what do they do with the data once the cold backup process is done? Glyphstock offers a cold storage service based on a high security certified robotic system that allows the storage of encrypted data in optical discs for offline custody during the necessary decades www.glyphstock.com

When trying to minimize downtime and unavailability, it is common to opt for a hot backup or backup because it can be done while users access the data, but if the data is altered during the backup, it will not be reliable and It can also affect the operation of the processes if it is carried out simultaneously with the use of them. With a hot backup the data is clearly exposed.
