Marco, indeed, our recommendations regarding this have slightly changed. I'm merging your post into the thread that should answer your questions. Feel free to ask for additional clarification though, if required.

Thank you, Alexander.
I think i got it. It depends... ;)

What i understand:
If i am not willing or able to do a surebackup it is still reccomended to plan a periodicall Active Full. Expecially if there is a long Backup Chain.

My Setup:
In my case i have about 25 VMs. I added Jobs for each Type of Windows-VM (Active Directory DCs, Exchange, File, SQL). All other Windows-Server are in one Backup Job for best dedup experience. I do a Forward Incremental Forever (without a planned Active Full) and additionally a Backup Copy Job to another fire protection area. Additionally i created a SureBackup Job for each VM once a week. So if there will be detected an error i would do a manual active full.
This Setup fine? If i read the previous post, i think so.

And you setup looks fine.

[MERGED] Moving from Reverse to Forward Incrementals

Veeam Logoby Lagcat » Wed Jun 24, 2015 9:04 am

Hi All

we have always done reverse incremental but we are looking to change to forward speed things up for our backup window which always seems to get smaller and smaller

my question is:

if i run a synthetic every Friday - should i still schedule an active full weekly/monthly or does a synthetic do the job?

i don't want to only use synthetics if a few weeks down the line i hit problems and asked to do a active full

any advice on this - i could read through best practice but i would rather some use info back

Cheers

Hi Jake,
As described above in the thread, the best practice is to use Forever Forward incremental method with Surebackup. In this case you need to run active fulls manually in certain situations such as:
- If SureBackup detects unrecoverable backup, or backup file data corruption
- If you want to reduce VBK size (after rearranging jobs or deleting lots of VMs)
- After major upgrade of our software to profit from new enhancements
Please review the topic for more info.
Thanks!

- Or you have the standard edition of Veeam B&R which does not include Surebackup!

Not that good, but with Standard Edition you can still emulate SureBackup manually.

[MERGED] Are periodic full backups necessary?

Veeam Logoby cffit » Fri Jul 10, 2015 8:41 pm

I was doing forever incremental backups with weekend synthetic full for some time. Then our weekend synthetic full began to take a long time to build. I was told by support a while back that we should be doing periodic normal full backups or else this can happen. Do others out there do forever synthetic fulls only?

1. Is this a true statement?
2. If so, does that still hold true with v8 today?

I am starting to do backup copies offsite and it seems like they are forever synthetic fulls, so it got me to wondering.

Hi,

while its on the table i wanna throw in another question about the active full frequency. What i am missing (if it´s there, pls tell me) is that i can choose to have an (scheduled) active full every x restore points. Since the job is counting in Restore points and not in days, while the scheduling for active full does. Would make things easier in certain cases. Is this planned for future releases?

Regards

Hi,
There is not a lot of demand to schedule Full backup as each Xth restore point and it looks not difficult to calculate the number of restore points between Fulls.
Could you specify your use case, why do you need the option?
Thanks!

It´s not about difficulty to calculate, it´s about having to take care about it. If you for example agree to have a max. chain length of 15 (as a standard, when not utilizing surebackup) allthough you wanna keep a lot more restore points (50+), you will need to think about a lot more parameters than just one setting for having active fulls every x restore points like, actively scheduling for weekly, monthly - exclude include months, when does the job start according to included or excluded months, job runs aside from normal schedule, etc...

Thanks for the explanation.
We recommend as best practice to keep long chains offsite(at least another repository) using backup copy jobs.

The backup copy job has GFS retention policy which helps to organize weekly/monthly/etc. restore points.
In this way you don`t need to have a struggle with complicated backup job scheduling.
Thanks!
