Hello Veeam Technicians . I need your Recommendations .
We have to decide to buy an new Backup Storage for Veeam Backup to Disk followed Backup to Tape , because out Backup Storage has poor Performance.
Our Backup Storage at the Moment is an FAS 2554 from Netapp with 48 x 4TB SATA Harddisks and one Controller with an 4 Core CPU.
This Backup Storage is connected with the Backup Server over 10Gbit Ethernet.
The Tape Libary ( HP MSL4048 ) use 2 x HP LTO7 Tape Drives and is connected via SAS with the Backup Server.
On Weekend there runs two Backup to Tape Jobs which produces on Saturday Morning an synthetic Full Backup to Tape, followed by incrementals over the Week.
The Target is that we have at the End of the Week an complete Backup from the whole Week on Tape ( Synthetic Full + Incrementals ).
Our main Problem is, that the Backup to Tape Job on the Weekend, when the sythetic Full is created, needs very long Time.
We have an Processing Rate from only 80 MB/s for the one Job and 50 MB/s for the second Job.
Veeam told us that the Bottlenek is with 99% the Source. That means for me the FAS2554.
Normaly the LTO 7 Drive should have an write Speed from 250 - 300 Mb/s but as you can see on the Screenshot our Backup to Tape has an Processing Rate from 86MB/s .
When we copy an File direct from the Netapp NFS Share to the Backup Proxy then we have an transfer rate from around 600 MB/s . ( Screenshot )
What does Veeam on the Netapp while processing the Synthetic Full ?!?! Why i have only 86 MB/s .
Is it an Storage Problem or an Veeam Problem ? What can ( should ) we change to become better Performance for the Backup to Tape Job . What will be the maximal Write Speed for Backup to Tape with Veeam ? 300 MB/s ?
Thanks for Help .
