After completing the initial restore wizard, the backup browser starts for file level recovery and that's where it takes a minimum of 15 minutes to actually display the data (and mount the data I am assuming) and occasionally it times out with the message "Connection to Veeam Community discussions and solutions for: slow snapshots of Veeam Backup & Replication As a second test I just now started a file copy using the same veeam server at the same time as my current replica is still running, from same source san to same target san and I get a steady 2 MB/s. CPU usage runs at 30% for a while and disk seems to be idle, then the disk where the repository is goes up to 100% active briefly then back to 0% and the CPU goes back up. 1, Veeam B&R v11. When I start the job, it take over an hour before it will begin As Tom has already said, If we took local replication(1-proxy model) as an example, It wouldn’t make any sense to use compression, since whatever proxy method were to be used, compression and decompression Hello everybody, i have installed a new Veeam Backup & Replication server using v9. 181 Veeam installed in a VM and using virtual appliance mode For the incremental replication with CBT, Veeam only had to "Read" 885MB in 5:44 (344 seconds). All 3 sites have vSphere 5. 5u3 on 2x Windows Server 2016 hosts Replication jobs are CRAZY slow. 5 hours 18 mins "Merging oldest incremental backup into full backup file (42%)". Hi Foggy, The backup is done in SAN mode with a physical server. it performed very well during a backup operation (not a replica that is being slow). I tried other replication job and was about 54MB/s but then bigger replication job about 80GB again 12MB/s. The replication job rans with < 1mb/s and will take for 50 GB > 24 hours. 6 Ghz. After the v11 upgrade (up at our DR veeam server), the speeds are way slower. If Veeam would better report what the actual problem is I Product: Veeam Backup & Replication Severity: 3 Opened: May 8, 2020 22:54 VBR v10 (P1), VMware ESXi 6. However, at site #2 things are very slow. Veeam Community discussions and solutions for: Slow backup performance (source-san, target-san) of Veeam Backup & Replication The 3rd interval, and the one it is on now, is at about 22 hours in, processing rate of about 34MB/s and has read about 55Gb so far. I knew using the Veeam GUI may slow, so I simply copied the files from the C:\VeeamFLR folder. Maybe this is more of a It's slow anyway, but after wiping both cohesity units EARLIER this year, speeds were at least bearable. Each thread is independent, so after a single object has finished copying, the TCP connection is closed, and a new one is opened. Make sure the host with the veeam proxy and veeam server are linked together with the fastest link you have available. It is still not clear where this Veeam B&R server is located and what are the bottleneck stats for your backup jobs. We have just acquire an EMC DD2500 with DDBoost and Veeam V8 (with Patch 1 since yesterday) and backups are very slow. You may want to try this to get faster transfer speed: NETEX AND VEEAM SOFTWARE PARTNER TO PROVIDE FREE WAN OPTIMIZATION SOFTWARE FOR NEW VEEAM BACKUP & REPLICATION CUSTOMERS "With the new installation - ESXi 7. And yes i do have throttling rules set to 40mbps during the day. Veeam Community discussions and solutions for: *slow* FLR Restores of Veeam Backup & Replication Veeam Community discussions and solutions for: Slow Quick Migration on 10Gbit network of Veeam Backup & Replication Veeam is running as a VM. can you confirm that this is the cause the specific slow merge scenario i had reported? it did eventually finish merging last week. Is there any way that I can reduce the time it takes for the replication to complete, as our other VM that we replicate takes 30 sec and at most 10mins (Varies on the Veeam Community discussions and solutions for: Slow copy jobs over WAN of Veeam Backup & Replication I am currently trialing Veeam Backup and Replication and struggling with current process rate. Failover is just a switch from the original VM to its replica, while during replica failback to the original VM Veeam B&R needs to calculate and synchronize the differences between the original VM and the replica VM. It takes 2 - 3 hours to replicate less than 50 Gb of changes over a gigbit circuit. 5TB) show speeds in the 500MB/sec to 1GB/sec or more (fastest reported speed I've ever seen is something like 3GB/sec but that was on a 1. of Veeam Backup & Replication Veeam Backup & Replication stores all its configuration (backup jobs, available restore points, history, general settings, ) in a database on the Microsoft SQL Server. With the old setup (same setup but different hardware, using the same NAS for backup) it was much faster! (around 120 - 240MB/s). Veeam bottleneck statistics are accurate, you can trust on them when troubleshooting. I had to configure the proxies manually in order to make sure it doesn't try to chose proxy that will be going off-site when backup and replication seeding is completed. slow to open of Veeam Backup & Replication Veeam + Proxy Server: HP DL360 G7 with 60GB RAM and 6 (12 virtual) Cores Source: 2 x HP Dl580 G8 (But the Backup Copy Jobs don't touch this Servers) If anyone has an idea, what could cause this slow speed, i'd be glad for any suggestions. [MERGED] Planned Failback is Slow and Inefficent. We have two physical Exchange servers with approx. Disk latency at this point was around 30-40 ms. Wouldn't it be better if the files went straight from the repository/proxy to the guest, rather than going around the houses? For reference, I have 1 x physical Veeam server were the Veeam backup files reside and I'm using 8 x virtual Veeam proxies using hotadd (one on each host server). (1 HDD with 500GB and 27,7 in use) mhhh ok . What was slow? Well, first the startup of the GUI can take a lot of minutes. The VEEAM backup function at the same hardware runs with 50 MB/s instead. All the other VM's still run at their usual fast speeds. Re: Is my Veeam Backup slow or fast? Post by Vitaliy S. 3 to Veeam Cloud Connect 12. 2x FC switches, 5x IBM x3650 M3 hosts with 144GB ram each, vmware 5. Veeam keeps blaming the network, which makes no sense. The bottleneck is always displayed as target Datastores ! If Disk Utilization is below 50%, you can rest assured your NetApp is probably not the bottleneck and you should investigate the FC connections to your ESXi servers. we have been facing since upgrading to Veeam 12. - SATA 7200 is slow, very slow in terms of IOPS. But not the Backup Job itselves but clikcing around in the GUI. GUI was extremely slow. Not a support forum! Skip to content. 7u3, Windows 2016, Windows Defender A/V scanner Why is the scan so slow? Scanning via Veeam takes multiple times longer compared to scanning from within the VM. It wasn't always this slow, just started doing this in the last week. It's just those two who got slow. I'm using Direct SAN for all jobs. I can only confirm what Regnor & vmtech123 said. Then do a final replication like that to the secondary site. Not a support forum! I am using emc data domain as backup repository and i passed through and hba card on my veeam server (veeam backup & replication is a vm) and using DDboost my veeam I don't disagree that mtree replication is an option, however, I would disagree with the conclusion on this statement -- many clients are using Veeam and DataDomain for the same operations without such a speed limit, so, barring a problem on the DataDomain side with dehydration or the DDBoost library, I suspect the issue resides elsewhere.
