ReFS for Office365

[GabesVirtualWorld]

Hi, would it bring much to format the volume on which the Office365 backups are stored, with ReFS?

[Mike Resseler]

Hey Gabrie,

Not really. Since our repository is a running database, there will be no block cloning where you can take advantage off. It also won't give you a downside though (but make sure that your server has the latest updates to avoid issues with ReFS bugs).

Thanks!

What allocation size do you suggest formatting the drive where the O365 mailbox are going to reside on? Default or 64K or something else? I am going with GPT since this will over over 2TB drive one I am done.

Best Practice Guide:

Disk Repository

- Use high throughput low latency storage. Thus DAS or SAN are preferred storage volumes for repository. Go with the default controller and stripe size settings.

- Repository File System should be chosen as NTFS with default settings (4k allocation units).

- Do not enable storage encryption, dedup or compression on the repository volume for better performance

- Separate repositories by data type (Exchange, OneDrive, SharePoint) to allow higher flexibility based on the different data-change characteristics

- Avoid very large repositories because handling them gets harder. Distribute the backup data over several repositories, e.g. split by business units

- Keep 10% free working space per repository to avoid lock downs

What would you consider a very large repository? 1TB or more like 10TB?

More like 40-50TB ranges
