Hello everybody,

I have the following problem:
If I try to perform a restore to a share with the option "Copy To…", then I reach a speed of 25 mb / sec
If I try to perform a restore with the option "Restore -> Overwrite", then I reach a speed of 250 kb / sec

The restore I perform always on the same server
My user has Domain Admin rights

Veeam 9.0 with the last update

Does somebody has any idea?

Thanks and Greetings

This most likely comes down to the fact that if using the Copy To option, the backup is mounted to the remote console, not the backup server or repository, like in case of restore to original location.

Hi,

There actually is a relative easy solution to speed up restore (in cases where it really takes hours to start cause of the thousands of files you want to copy or restore). I'll try to take it step by step (an we're still on 8, so it might be a bit different)

1. Setup SFTP access to your Multi-OS FLR (https://www.veeam.com/kb2062)
2. Get IP of FLR (also on https://www.veeam.com/kb2062)
3. Download a statically compiled rsync (https://www.symantec.com/connect/downlo ... -rsync-307)
4. SCP it over to your FLR
5. Use rsync :)

It would be easier if Veeam would include rsync in the Busybox installation by default though.

We also had some issues with restore speed using File Level Restore.
As a workaround, I did the following:

    1. Start Instant VM Recovery of the VM, but do not power on.
    2. Edit setting of the VM where you want to restore the files,
    add the disk of the restored VM (in Veeam NFS Datastore)
    3. Now the backupdata is available in the VM, and you can restore with robocopy.

The big advantage is that restore is done locally, so there is no network traffic.
Also, if Veeam server is in another VLAN than the VM where you want to restore to, traffic doesn't need to be routed...

I wonder if it isn't possible for Veeam to implement this in the Veeam GUI as an extra option when using File level restore...

[MERGED] Slow restore speed

Veeam Logoby hyvokar » Mon Oct 16, 2017 8:01 am

Hi!

I need to restore about 10GB worth of data to our web server.
The data consists ~1.5million files. The restore speed I see is 100-200KB/s, and the restore will take for ever.

The data is being restored from older 12x 10k sas raid5 to not-so-old 12x 10k sas raid6 via 1Gb ethernet.
We have physical backup server with 2x xeon E5507 processors and 48GB mem. The backup storage is connected via FC.

Is this kind of performance expected?

I recall asking this before, but would it be possible for veeam to rar guest windows files, so I could take the rar to the web server and unrar there, preserving file attributes.

Yes, file restore sucks, you wont get much response on here as everyone knows how bad it is. It's the only reason we still have to keep Commvault for our file servers.
