![]() ![]() Weekly, monthly and yearly backups are also called archive backups. In the GFS retention policy, weekly backups are known as ‘sons’, monthly backups are known as ‘fathers’ and yearly backups are known as ‘grandfathers’. GFS is a tiered retention policy and it uses a number of cycles to retain backups for different periods of time: Ransomware and security flaws, like the recent Apache's log4j Java vulnerability, can put many. The 3-2-1 Rule as we know it says the following: There should be 3 copies of data. GFS backups are always full backup files that contain data of the whole machine image as of a specific date. That's why 3-2-1 backup rule by Veeam is evolving into something up-to-date to today's conditions and today's risks. When you configure the GFS retention, Veeam Backup & Replication creates weekly/monthly/yearly full backups, so instead of one backup chain consisting of one full backup and incremental backups, you will have several backup chains. Also, one corrupted increment can make the whole chain useless. Large number of subsequent incremental backups can increase recovery time, because Veeam Backup & Replication has to read data through the whole backup chain. The GFS retention also helps you to mitigate risks that the short-term retention policy has, such as large number of subsequent incremental backups. Depending on which flag is assigned to the full backup, it will be stored for specified number of weeks, months or years. These GFS flags can be of three types: weekly, monthly or yearly. For this purpose, Veeam Backup & Replication creates synthetic or active full backup files and marks them with GFS flags. Just make sure that you do some research into the service provider to make sure they meet your compliance requirements before signing a contract.The long-term or Grandfather-Father-Son (GFS) retention policy allows you to store VM backups for long periods of time - for weeks, months and years. Backups are as safe and confidential as they would be in a dedicated off-site repository, so that data of all types is completely protected and easy to recover. There’s no separate console, and data is fully encrypted at every step. It’s as easy as selecting a service provider and pointing backup or replica jobs to the cloud with a few simple clicks. Veeam Cloud Connect makes it easy to get backups and replicas off site to a Backup as a Service (BaaS) or Disaster Recovery as a Service (DRaaS) provider such as BrightCloud, without the cost and complexity of managing a second infrastructure. There’s good news here for Veeam customers, because Veeam Cloud Connect makes this incredibly easy. ![]() You could do this by storing a backup in another office, shipping tapes off to a storage facility, or by having a copy in the cloud. This prevents a local disaster such as a flood or fire from damaging all the copies of data. ![]() The last and perhaps most often overlooked rule is keeping one copy off site. Different mediums also provide different forms of credentials that may not all be tied into the domain. Spreading the data across different mediums also makes it much harder for ransomware to infect every backup. Two devices of the same type have a much greater risk of failing around the same time than two devices of different types or two different storage media. Your backups need to be on at least two different media types such as tapes, hard drives, or the cloud. Understanding how the 3-2-1-1-0 rule applies to your backup strategy when setting up jobs Grandfather: Backups are kept for a year. Ask yourself “If this hardware dies, are there still two copies of my data somewhere else?” Always be mindful of the storage that your backups are sent to, so you don’t have a single point of failure. If you have two copies of the data on the same storage device, and the hardware fails, then neither backup is going to work. You should have three copies of your data spread across different underlying storages. ![]() The 3-2-1 backup rule is a celebrated backup strategy which stands for: How Veeam Cloud Connect Helps With the 3-2-1 Backup Rule June 1st, 2021 by Kris Price ![]()
