The folder is still containing 1,68 GB of data files, 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. I'm having similar slow restore issues, but restores are going across the LAN as far as i know 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. Complete answer from Support: We are aware of the low performance while restoring multiple small-sized files via Windows FLR.

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

Easier and decent speed for me. 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. At gb that is going to take forever. I ran into this once before and after working with support it looked like it may be related to having an orphaned user with permissions to the files.

In this case there were no orpaned users. I can restore the entire VM very quickly from the same backup so I know it is not a problem with network or disk.

We've had quite a few complaints on the forums that networkless restore of a large number of small files can be very slow. Our developers took a closer look at the issue, identified primary bottleneck, and redesigned the way how multiple small files are restored in v7. According to the most recent build notes, this change resulted in up to 40 times restore performance increase! Before somebody asks, Linux FLR had similar issues restoring a bunch of small files over the network, but those were caused by a different problem, and this was addressed in v7 as well up to 50 times file restore performance increase.

Pretty amazing stuff! Without this improvement, I've got people telling me I need to dump Veeam for netbackup. Will V7 restores run at good speeds using v6 backups or only with backups done with V7?

Right now my only workaround is to do an instant recovery and robocopy the files to the original location. Not exactly the one click restore I need to allow operators to restore files when I am on vacation.Post by edv rubner. Post by marc.

I expect we'll continue to enhance the performance of the file browser over time, but it's pretty hard to be these tools for now and robocopy has been a native part of Windows since R2.

It ran for 3 hours and nothing happened. I then canceled, restarted the FLR restore and copied just a few folders and it works, but it's very very slow. There are hundreds of subfolders in hundreds of subfolders. It's just unusable as a solution. Is there anything I can do to speed this up. I'll try to FTP them from the linux box to Windows and see if that helps.

Just let it run after hours and it was successful but it doesn't sound right to me. I can download from our online backup service provider quicker than this!

Any suggestions as to where I might start looking for a bottleneck? What version of VBR are you at? Try to update to the newest version. There were a some improvements in FLR performance tehre.

So its going to take about 4hrs. This is to recover a ransomware attack. We use both Veeam and Commvault, Commvault is much quicker restoring so this isn't a OS specific thing, its a Veeam performance thing.

Next time i will try the "VeeamFLR" folder.You can set up Veeam Agent for Linux to create file-level backup. The file-level backup captures only data of individual directories and files on the computer. You can use the file-level backup to restore files and directories that you have added to the backup scope. With Veeam Agent for Linuxyou can specify which files and directories to back up:. Veeam Agent for Linux does not back up e xtended attributes of backed-up files and directories during file-level backup.

Many storage arrays use a default stripe size around 32 or 64k. This is because they have to be a general purpose solution able to manage at the same time different workloads: datastore for VMware volumes, NFS or SMB shares, archive volumes. Since in many situations the different volumes are still carved out from the same RAID pool, this pool has a unique stripe size value.

Top 15 Veeam Backup & Replication Performance Optimizations

Again, as explained in the whitepaper, thanks to compression these values are reduced to half when the block lands into the repository. So, we can assume the default block size written in the repository is going to be KB. Bandwidth is going to be Say you have to transform 1 TB of data, you need to move 2TB of blocks. If you change only the storage stripe size to for example KB, the new bandwidth will become 40,51, three times the previous one! This means the same backup job will last 6,86 hours.

Compare it with the previous result of 20,6 hours, and you can immediately understand the importance of configuring the right stripe size on your Veeam repository. Also, the RAID level is important. You can see again in the tool the reason. But again, remember to carefully evaluate these configurations options when you design a new storage for Veeam backups. I was wondering if the storage stripe size can have a higher value than the veeam block size. What are the tradeoffs of configuring a extreme high value of the storage stripe size?

For example,with NTFS the maximum block size is 64k, so any windows repository will use at most this value. Thanks for sharing all this with us. Using the calculator on 64k stripe size against our soon-to-be environment the bandwidth is 8. On NTFS I always use 64k stripe, and also check if the underlying storage is using the same size to be able to align blocks. The final result depends on many other parameters like number of spindles, storage raid chosen….

Okay thanks. Ok good. C: would be on the default 4k cluster size. I would like to keep Veeam backup files separate for simplicity. Thanks for your help so far. The important part is that the volume used as Veeam repository has the 64k stripe size, other volumes are not important in regards to this setting. If I understand well.

All backups are fine with Application aware. This is when restoring a folder of 20 MB with 50 files in it. The VM is a Windows server R2. Should it be this slow!?

But the permissions isen't preserved! I restore the files locally to Veeam backup server. So, this looks like to be environment-specific issue in your case. I recommend opening a support case for further troubleshooting.

What about permissions. So the permissions is backed up. But when copy the files the permissions is lost. If yes, than the file is copied normally over the network. While the guest interaction API is definitely much slower than direct network operation, you should still be seeing at least times faster speed than you do Please open a support case for investigation. Please open a support case for troubleshooting. Re: Very slow file level restore and problem with permission Post by Vitaliy S.

We have opened the following ports: udp, udpudptcpI can send and recevice files so everthing works good in Windows. But when trying to restore files from Veeam to the target vm it does not use the network.

What are we missing? Backup speed is fine, it is only the restores. Are you using Other OS restore wizard or Windows one? I have done restores to the backup server itself and back to the original location.

This is with the Windows wizard and with the Other OS. I want to specify, this is only if we restore multiple files or entire directories. If it is a single file, the restore is quick. Can you please copy any small backup file if you have it of course to any other place and try to restore any file once again? If not I would also like to add that we have the same issue. Restoring Guest files windows is very slow!By default, backup jobs write VM data to the backup repository in one write stream, and store data of all VMs to the same backup file.

Such behavior can be non-optimal if the target storage device is able to write data in multiple streams simultaneously. In this situation, the backup repository may become the bottleneck for the data transfer, even though its resources will not be fully utilized. In this case, the backup job will use a separate write stream for every VM in the job, and store data of every VM to a separate backup file.

Resources of the storage device will be used more efficiently, and the job performance may increase. To create per-VM backup files, you must enable the Use per-VM backup files option at the level of the backup repository. It is recommended that you enable this option for deduplicating storage appliances that support multiple write streams. The option is also enabled for scale-out backup repositories by default. It is recommended that you balance the number of tasks on backup proxies and backup repository to avoid the situation where some backup infrastructure resources remain idle while others are overloaded.

It is not recommended that you disable the Limit maximum concurrent tasks to N option for backup repositories with per-VM backup chains. In case of per-VM backup chains, synthetic operations synthetic full backup, backup files merge and transform work in parallel for every VM in the backup.

The number of parallel operations is limited by the number of concurrent tasks that can be performed on the backup repository. If you disable the Limit maximum concurrent tasks to N option which results in using an unlimited number of slotsthe load on the backup repository may be high. You can enable or disable the Use per-VM backup files option for existing backup repositories at which backup jobs are already targeted.

The new setting will not have any effect on previously created backup files on the backup repository. It will affect new backup files created after the setting is changed. Synthetic full backups do not affect the Use per-VM backup files setting. Our website uses cookies!

I get quicker restores in my home lab, so I am curious to see what you are restoring to and from - it's not a VM on the same disk as the host is it? I can't understand. Attaching a disk from another server is simpler than restoring the entire file subset - if your OS is part of the same disk then this is likely to cause issues, so restoring files is the only option.

Backup one of my servers and start to do File-Restore. Slow may be happen if you have VBR server placed offsite from the repository and datastore where you restore to. In this case traffic goes over the network back and forth. Starting from v9 Veeam gives an option to restore locally with the restore proxy. To continue this discussion, please ask a new question.
