Very slow file level restore and problem with permissions

Re: Very slow file level restore and problem with permission

I did a instant VM recovery, and copied the InetPub folder over the network. The folder is still containing 1,68 GB of data (59137 files, 6324 folders).
The transfer speed was much better. We got 27 Mbps.
However, this is not a practically way to restore files "on demand".

In addition, in a production environment doing a instant VM recovery is not possible. Then we would needed to setup and start a SureBackup job.

Any other ideas?
If not i guess i have to open a support ticket.

Could you please explain what changes you made to your setup? I'm having similar slow restore issues, but restores are going across the LAN as far as i know...

Are you refferig to my post?..
I made no changes, just used different methods for restoring.

Instant VM recovery is not always a good option in a production environment, sure backup takes long time to get up and running.
I would lilke the normal "Restoring Guest files (windows) " to just work at decent speeds.

I recieved an answer from Veeam suport regarding this issue (case 00203915)

Support confirmed that they were aware of the problem, and provided a workaround: OtherOS FLR with FTP
Although this is a bit more timeconsuming to set up, the restore/copy speed was much faster, and totaly acceptable.

Complete answer from Support:
We are aware of the low performance while restoring multiple small-sized files via Windows FLR. This behaviour will definitely be improved in the future versions of Backup&Replication.

As a workaround here I suggest using OtherOS FLR with the FTP enabled. I've just tested it in our test environment and was able to get decent speed and restore some files with Norwegian symbols in their names. Basically, you just need to connect to the FLR aplliance's IP through FTP protocol using Windows Explorer or any FTP client you like and copy the files to original or any other server.

Could you please try this method and tell me if it works for you?

Same answer as I got, though I use "CopyTo" instead of "Other OS FLR with FTP". Easier and decent speed for me.
Here's my short thread by the way: Windows FLR "Restore", max number of files?

I tried CopyTo as well, that was also way to slow. Only thing that gave me decent speed was with FTP.

This seems like a serrious issue with a basic function that needs be addressed.
We dont restore VM's on dayly basis, but files and folders gets restored almost every day.

[MERGED] : Restore Copy to

Veeam Logoby AlexWhit » Mon May 27, 2013 8:42 am

I wonder if anyone can help. i am trying to restore some files to a new file server using "copy to" when this is running it seems to be really slow. it will stick on a word document for a long time then carry on. it is at about 1 - 2 MB/s and can drop to 362KB/s. At 138gb that is going to take forever.

thanks for any help

Hi, Alex. Are you running “Windows OS” restore? If so, can you kindly run the “Other OS” type of restore and see what speed numbers you get there.

Thanks.

For now this is the best strategy, indeed.

It has been confirmed that there might be some issues while restoring number of small files though Windows OS restore.

According to plan, this problem will be addressed in the upcoming product release.

Thanks.

there are far to many files to reset all the permissions. i will just try robocopy from the old server.

thanks

I just had a look at that but i need to preserve the Ownership and file access permissions.

While doing Other OS restore there is a tick box called “Preserve permissions and ownerships”. So, using it in order to keep original permissions settings for recovered files.

Thanks.

I believe this option is available for Linux hosts only.
