How can I guarantee cloud-to-cloud data backup security? Cloud-based backups for VPS cloud cheap Vietnam can be secured via many methods.
Backup software and erasure coding may be just what is required to improve your cloud-to-cloud backup security. There are a lot of ways to ensure the security of your cloud-to-cloud data backup. One popular choice uses backup software to encrypt data prior to transmission.
A drawback to this approach is that the encryption keys have to be backed up to an alternate location. If this does not happen, a data loss event could potentially result in the loss of the encryption keys, thereby making data restoration impossible.
Another approach is to use a cloud-to-cloud VPN which creates an encrypted tunnel between the two VPS cloud Vietnam. This tunnel can be used to ensure privacy during a cloud to cloud data backup.
In addition to protecting data while it traverses the internet, data have to be protected once it is sent at its destination. Storage-level encryption is maybe the most popular option for protecting data at rest.
Cloud-level erasure coding is another way to protect your cloud to cloud data backup. Erasure coding distributes write operations across multiple disks, not unlike a RAID array. There are many different types of erasure coding, like the bunch of redundant independent clouds (BRIC) architecture that allows data to span multiple public clouds. While this may, at first, seem like a way to ensure only redundancy, erasure coding can also be used to improve security.
Many BRIC implementations, like Tahoe-LAFS, allow data to be structured in such a way as to provide both privacy and redundancy. Cloud-to-cloud data backup privacy is achieved by virtue of the fact that none of the public VPS cloud Linux providers used in a BRIC architecture has a complete copy of your data. As such, the public cloud companies have no way of accessing your sensitive content because they only have fragments of it.
The primary disadvantage of using a BRIC architecture is cost. To protect your backup data in this way needs several public cloud subscriptions, so costs can quickly add up.
