For example, using 4TB drives, they can achieve a cost per GB as low as $0.036. Storage pods are designed in-house by Backblaze, leveraging consumer grade hardware and hard drives in a purpose-built chassis designed to minimise costs, reduce footprint and yield the best dollar per GB possible. Backblaze has evolved this object storage service ‘B2’ out of the already successful $5 a month unlimited backup plan which was built from the ground up using Storage Pods. Phase 3 – Configure Veeam Backup Repositoryī2 Cloud Storage is an object storage service offered by Backblaze that enables users and organisations to upload files to their heart’s content billed on a per monthly basis using a pay for what you consume model. Weekly, monthly and yearly backups are also called archive backups.Phase 2 – Install and Configure Synology CloudSync 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:

GFS backups are always full backup files that contain data of the whole machine image as of a specific date. 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. 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.
