Backup methods

[marius roma]

I recently updated from version 7 to version 9 and I see that the description of backup methods is slightly different.
I use 2 kind of NAS as repositories, a generic NAS and a NAS with deduplicating fratures.
How can I detect wich backup method I should use for each repository in order to optimize the use of space and/or the speed of jobs?
Is there an up-to-date document I can refer to?

Hi,

Could you give some examples please?

Although there are improvements "under the hood", the previous recommendations are still valid. Also you might be interested in a BitLooker option (threads that describe how the thing works: 1, 2)and per-VM backup chains.


Thank you.

You can compare the screenshot on page 81 of the "Veeam Backup & Replication - Version 9.0 - User Guide - VMware vSphere Environments - February, 2016" with the screenshot on page 231 of the "Veeam - Backup & Replication Version 7.0 - User Guide - VMware Environments - January, 2014".
You will see that the description of the Incremental backup is different.

Ok, now I see.

Incremental mode has been improved since v7 - Forever-Incremental" mode was added. It allows you to save space (intermediate fulls are optional now) and acts like reverse reverse-incremental I hope that this addresses your question, otherwise feel free to ask.

Thank you.

Thank you for the clarification.
Let me ask for some further details.
Given I have both deduplicating and non deduplicating NAS repositories,
- what is the best method to save space on non-deduplicating repisotories?
- what is the best method to save time on non-deduplicating repisotories?
- what is the best method to save space on deduplicating repisotories?
- what is the best method to save time on deduplicating repisotories?
Thank you

- what is the best method to save space on non-deduplicating repsitories?
- what is the best method to save time on non-deduplicating repisotories?

These two are mutualy exclusive - increasing the deduplication and compression ratio will increase job duration. Please find more info on page p101.

- what is the best method to save time on deduplicating repisotories?

Stick with simple Forward-incremental mode. Do not use forever Forward Incremental, Synthetic Full, and Reversed Incremental. More details in
best practices for dedup.appliances.

A good practice is to use non-dedupe storage as a primary backup destination and use dedupe storage as a secondary backup destination for backup copy job chains.

Thank you.
