365 Exchnage email backups, slow, timeouts

Post by pcdocnz »

Hi.
I'm doing some test email backups in our workshop before I install Veeam for 365 onsite at my clients office

Backing a a/s with few emails : no issues
Backing up a 2nd a/c with alot of email : very slow, and timeout issues.
In the Veeam Backup program, its showing " bottleneck : source" . "Processing rate 2.7MB/s"
"read rate" anywhere from 0B/s 1.5Mb/s "

Is this just MS's 365 throttling ? I know MS do heavily throttle PST imports in 365 , but throttling read access ?
Is there anything that can be done to speed this up, and more importantly to stop timeouts ?

Hi PC Doc NZ and welcome to the Community!

Exchange throttling occurs per mailbox, and with 1-2 mailboxes in a job, it can impact the speeds significantly. If you try it with, say, 15-20 mailboxes, the read rate should improve.

Hi
I had many timeouts due to inactivity , requiring a manual re-connect .
Is there an option to auto re-connect to 365 .

Pop up box in veeam shows
"Because of inactivity, your connection to the Veeam backupfor Microsoft Office server has timed out. Do you want to reconnect"
https://helpcenter.veeam.com/docs/vbo36 ... tml?ver=40

If the product wont auto-reconnect to complete the backup , then it really cant be relied on to compete scheduled backup .

The message you are receiving is just the console that closes to reduce load on the server. You don’t need to have the console open to perform the backups. This is only used for the configuration and performing restores.

Backup jobs are running in the background so everything happens in the background as long as you enable a schedule. As Polina said, if you backup multiple mailboxes at once, the performance will increase.

If you get actual time outs from the VBO server to O365, you will see this in the backup job log.

Next question.
I want to be able to run the 365 exch backups on PC1
Then do the restore (to PST) from PC2
(I have reasons : 64b Outlook cannot be installed on PC1 , 64b Outlook needed for recovery to PST).

So far, I cant get the software on PC2 to see the repository on PC1 . Share access is OK . Firewall disabled for now .
Alternately , if I copy the repositry tro a USB Hard drive, can I EASILY recover using that copy of repository thats on the USB Hard Drive

So, can I only recover on the PC that did the backup ?
Thanks

Ive managed to access the repository from another PC (user error, was putting in wrong credentials)

A search here found that the repository cant be (easily) copied to USB, so I'll look at adding a USB Hard Drive as a secondary repository.
Thanks

Using a USB hard drive as a repository is not really advised. We use a live database so direct attached storage is the best practice. Detaching and re-attaching can lead to issues with the database/repository.

It would be advised to leverage a server/computer which can meet the requirements for this.

Can the database/repository be backed up as part of a normal Windows Backup ? Just using the built in Win Image & file backup (or the Veeam backup)

Will the database backup , or will it stay locked & not get backed up ?

You can use the Veeam Agent for Windows to back up the VBO server or Veeam Backup & Replication if the server is virtual.
