Best Practices Cyber Protect

Thread solved

I have about 700 GB of data I want to backup and a 4TB USB backup drive (and also a secondary NAS backup).  What is the Best Practice for a Backup scheme?  I use my Windows PC daily and at the end of the day would like to back up any changes.  I would like to stay with the 4TB USB and not have to get a larger drive unless necessary.  So, should I use Incremental and if so, how often do I make a full version after how many incremental versions?  And how many Versions should I be storing?  What is Version Chain scheme as opposed to incremental scheme?  Is there a best practices document on the web anywhere I can find?

Stephen,

Welcome to the forum.

Here is a blog post that covers some of what you ask for.  A Version Chain scheme as you call it is simply the number of backups that are specified in a backup task before automatic cleanup rules are applied or a manual cleanup of backup files is performed.  In general terms a Version Chain should not be allowed to grow to large especially if using an Incremental backup scheme as incremental scheme have dependencies between them that can hinder recovery in some cases.  I practice a daily incremental scheme backup with a full disk version every 2 weeks and only store no more than 2 Version Chains which causes an automatic cleanup every month.  That cleanup consolidates all incremental files into a new full backup.

You may need to cleanup more frequently or less dependent on how much data you generate over a given time period.
