The main backup purpose is to protect your data against disasters and VM failures. However, having one copy of a backup file does not provide the necessary level of safety. A backup file may get corrupted or lost, leaving you with not data to restore at all.
Backup experts claim that to build a successful data protection and disaster recovery plan, you must follow the 3-2-1 rule:
|•||3: You must have at least three copies of your data: production data, backup and its copy|
|•||2: You must use two different types of media to store copies of your data, for example, disk storage and tape.|
|•||1: You must keep at least one copy of a backup file offsite, for example, in the cloud or in the remote site.|
Thus, according to the first statement of the 3-2-1 backup strategy, you must have at least two independent copies of a backup file in different locations. In case a disaster strikes, multiple backup copies increase your chances in data restore.
To let you adopt the 3-2-1 backup strategy, Veeam Backup & Replication offers backup copying capabilities. Backup copying allows you to create several instances of the same backup file in different locations, whether onsite or offsite. Copied backup files have the same format as those created by backup jobs and you can use any data recovery option for them.
Backup copy is a job-driven process. Veeam Backup & Replication fully automates the backup copying process and lets you specify retention policy settings to maintain the desired number of restore points for copied backups.
