In the screenshot we see a very high latency (last column) of seconds (!!!), which is too slow for the mentioned disk type, veeam agent reads the most data of all While the proxy is reading the data to back up, the production VM experiences higher I/O latency. Hi I've been battling this for around 2 months with HPE and Veeam Tech support One issue was that VM's with many hard disks get really slow e.

I am verry close to just giving up,and let read whatever it wants Fast Clone is the Veeam Backup & Replication technology that helps create quick file copies. Deployment is fully automated. This is more or less Of course, changing the disk size will cause veeam to merge all restore points (=snapshots) of the replica and to calculate the digests for just transfering the deltas between source and target vm. On disk 1 it reads only the used space, on disk 2 and 3 it READS the entire disks. So Veeam does a full read, and CBT still works but kicks in for the subsequent runs after this one. 0, For some background - The source volume is being read via SAN mode (1/22/2018 6:02:30 PM :: Using source proxy 192. 5 TB) 1.

I got the same During the most recent backup (incremental), the read speed was 174 MB/s on drive C and 83 MB/s in drive D, but for the current job in progress those speeds are 36 MB/s and 22 MB/s . If I recall correctly, I remove the disk from the VM, and then add it back as an existing disk, and once it’s showing correctly, then Veeam can grab the disk for backups. From previouse restores provided by the windows-built-in backup tool recovery was always very fast and I think this should be the goal too.

Usually when I see a 0B disk, it’s actually a VM issue and not a Veeam issue. Plus I don't even see much read/write bandwidth (maybe 15-20 MBps each) in Resource Monitor, just that the "Active time" of the external hard drive is at 100%. I've had some jobs take 15 minutes to start wheras one job has took 40 minutes before starting. m. I can't configure that in my opinion. Assuming you are using a gigabit connection on the first host, your connection from the second host (slow one) to the SAN may not be using gigabit connection, rather 100mbit. 5 . Your direct line to Veeam R&D. Our secondary backup proxy takes upwards of 10-20 minutes to start reading data from the hard disks using CBT. That would mean the USB 3. Veeam Server is physical with an iSCSI connection into the iSCSI network and has all mirrored DataCore ESX virtual disks presented to it in Read Only mode. Simply expand ESX and browse to vmfs folder, then copy the file and paste it into "My Computer" local hard drive disk. 0, utilizing both backup jobs and replication jobs. SQL sever involves high iops so the host drives may already Been under load when the vm disks are mounted into the veeam proxy to read. Everything’s functional. The read speed will depend on change blocks placement: the more random they are, the slower the changed blocks will be read from source storage. 8GB Transfered 46. 3 GB read at 73 MB/s [CBT] Disk Backup was done from a none deduplicated NetApp volume.

This is blowing our backup window and causes backup-replication scheduling conflicts. check to make sure not out of disk space as the agent will use VSS to create a shadow copy of the disk which requires some free disk space. If performance returns to "normal" then at least you know the problem is with the CIFS portions writing to the D2D, if not, then you know it's almost certainly the source data retrieval.

Backing up locally to a Windows 2012 Veeam Server with Direct Attached Disks (MD1220) and Direct SAN access is giving me good results BUT when i replicate to our DR site the replication is really slow, even the incrementals is taking hours. But if we do a FLR or a bare metal recovery, performance will be very bad in the end. This is my go to test if I want to do a very quick basic storage performance test. Our primary Veeam server also has the backup proxy installed and when backing up a virtual machine starts reading the hard disks (vmdk files) within a minute or so of starting the job.

I have to reboot the server to get it to clear. At some point in the past month just after a client update, the read speed of the C drive has slowed down to ~8MB/s from a previous read speed of 150MB/s+. 0u1d (soon to be updated to U2)-----ReFS seems to be quite a bit slower than NTFS. Here’s a summary: 2 ESX 5. Btw, what is the RAID configuration on the target host? We are having massive issue trying to backup a server for customer; the server has Windows server veeam agent installed and protects OS and SQL; the backup job when runs takes over 20 hours and then it fails due to different reasons; we only have had very few successful backups and many failures; The server has SQL and some custom script populates I believe that is the expected behaviour of Veeam, as you are changing the disk configuration for the VM even though you are just adding a new disk. 3 ms Backend disk is 64KB ReFS on a R5 512Kb striped SSD array.

Veeam take 4 hours to backup each of those two VM, while should be lightning fast because the disk are empty. There is no way the entire contents of the drive changed Now that I look at this it appears for many of my backups Veeam is re-reading the entire contents of the drive as changed. The 2nd hard disk is 150GB in size its been calculating digests for 7 hours now and is only 3% of the way I'm contacting NAS support and will probably contact Veeam support on this - we are still seeing slow write performance on reverse incremental on the 12 and 16 disk NAS devices in use (right now as low as 4MB/s).

You could try to force network mode for the target proxy and see whether the processing speed becomes better (hotadd can put high I/O load on the target in some cases). The disk is at under 50% capacity, and from Task Manager CPU is at ~25%, RAM (32GB) is at 60%, the disk fluctuates between 0% and 20% utilization, with the disk transfer rate at 0, peaking The storage can be local disks, directly attached disk based storage (such as USB hard drive), or a iSCSI/FC SAN LUN in case the server is connected into the SAN fabric. Since I need to back up the entire VM and run pre/post job scripts, I created a B&R managed agent job for it. In our environment we have dual 40 Gbe to the switch and 10Gbe to our repo and multiple sans. Common misconfigurations are around MPIO setup, misbehaving HBAs and non-optimal RAID caching. The requirement is to move VM03 from Job #1 to Job #2 due to runtime scheduling and use of a slow WAN link. Setup replication jobs to replicate the VM's, the jobs run REALLY slowly - eg; hard disk 1 is 15GB, it took 16 hours to calculate digests then 35 minutes to replicate the changes. And speaking of reformatting the drive, if I copy all my files to a temp disk, then I downgrade my system to 21H2 and reformat refs volume, and then copy all my files back to the refs volume, not changing the physical disk and drive letter, will Veeam recognize the refs disk as the old drive and continue incremental backup or Veeam will found Veeam Community discussions and solutions for: Failed to open VDDK disk - is read-only mode - [true] of Veeam Backup & Replication. The Veeam application If you edit the VM and look at the properties, does it show the disk properly there? Usually when I see a 0B disk, it’s actually a VM issue and not a Veeam issue.
