Backup methods

Veeam Logoby marius roma » Wed Mar 23, 2016 10:27 am

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?
Regards

Hi,

I recently updated from version 7 to version 9 and I see that the description of backup methods is slightly different.
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

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.
