Freimmientis36 Swisscom has also already lost data. So talking about hyper-secure is very risky.
A solid backup concept is often based on the well-known “3-2-1 rule”. We show you what this involves and how easy it is to implement.
What does the 3-2-1 backup rule mean?
The 3-2-1 backup rule provides for the following backup strategy:
3: Three copies of all critical data
- the first copy is the original file you are working with
- the second copy is the local backup, e.g. on a USB data carrier
- the third copy is the cloud backup, which also ensures geographical separation and increased security.
2: Two different media/data carriers
Do not create the local backup on the internal system data carrier, but rather use a separate (external or internal) data carrier.
1: A copy of the data should be stored at a geographically separate location (offsite)
This is where cloud backup comes into play, as it can ensure geographical separation and greater security. The geographical separation is intended to ensure that the data can still be restored in the event of water damage, fire damage, theft or loss on the customer side, and the security measures in cloud data centres such as ours guarantee even greater protection against malware and hacker attacks.
