Full backup file could be heavily fragmented if you used forever forward incremental (no active full scheduled) or reversed incremental chain. Since the Veeam backups are already compressed, LTO-8 theoretical write speed in this scenario would be 360MB/s, if I understand correctly. My suggestion is to draw a data flow diagram with every NIC, HBA, and Switch listed and check if all ports are set to MAX speed, Jumbo Frame and use Tape/Library tools to check for drive performance. I am currently using Veeam Backup and Replication (10. Since half the I/O is used for reads, the amount of data that needs to be moved is double the size of the backup file.

Veeam is configuerd as an all virtual solution with 1 veeam backup server and two backup proxies, each server has 2vcpu and 4GB ram. R&D Forums. The backup speed is under 1 MB/sec. This creates additional time/work to leap-frog our backup files from repositories to the tape server, then backup to tape at speed, administrative overhead, oh and we don't have enough room to use the tape server as a repository anyway. We run nightly reverse increment backups that usually finished in 6 hours, now finishing in almost 12 hours. Create a backup for one machine, write it to C drive, backup to tape from there. I'm trying to, and have spent £1000 on disks for the backup target (QNAP) so I can do RAID10, but to be honest, I'm regretting that already as the backup speed is pretty much the same as it was with RAID5 disks, which suggests either the QNAP itself has a difficulty processing the data, or the bottleneck of "target" is a lie! Ok, I know the best way would be a physical machine with an FC card connected to the EVA. Both hard disks are located in different datastores and LUNs, but physically are located in the same NetApp RAID-DP SAS-disk-aggregate.

That is, if your device is low on Memory (RAM), it may use the pagefile, and this can hamper the performance of your So there is no chance of high speed backup with veeam without altering my environment? Generally speaking, network mode is recommended with 10 GB Ethernet. We have a 100Mbps fiber line which I know isn't the fastest but its also not slow. the speed can be reached to 300 MB/s, before the backup copy jobs started, the speed down to 10 MB/s after the backup copy jobs stared. iSCSI LUN added to the Veeam VM Media Server (Which also act as a repository server) end up having speed range between 50~87 MB/s. Without backups on a different system (preferably placed at another site), you will eventually lose data! A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup. I've looked at the VM's and ESXi hosts and can't find anything different in any of the performance monitors from Site#1 to Site#2. Been engaged with support since 2nd April.

Due to the extreme low performance backup of that maschine takes between 11 and 16 hours for 4 disks with 40GB, 200GB, 300GB, and 20GB. It is also well known that the way VEEAM reads the images is slow. When looking at the past Veeam backup job history I did notice a certain trend, which is why I discovered this issue at the first place. My processing rate rarely reaches 30 or 40MB/s. With the old setup (same setup but different hardware, using the same NAS for backup) it was much faster! (around 120 - 240MB/s). When using preferred networks in Veeam you choose to use another than the default host network for backups and restores. As far as network trafic over WAN, it should only be doing a regular incremental. I checked the backup summary and it shows.

Unfortunately, the internet connection is only 8Mbit (symmetric). Veeam backups on a very similarly configured R420 and R530 running busy VMs to the same or an identical Synology were fine, about 110-115 MB/s - wire speed, really. I would like to ask for your help identifying the following issue : Restoring a backup is dreadfully slow at 15Mb/sec. And the tape job does not archive any incremental backups and also does only process the latest backup chain. Is that acceptable speed?

It can write backups at almost full 10GB/s speeds. 10Gbit NIC for Management, vMotion, VM Traffic see that a full backup in nbd is 3. I am noticing though that when I am backing up I am getting 26Mbps speed and I thought that I would be getting faster speeds than that. High read latency on the source disk sub-system They have special tools to emulate data read in similar way as Veeam does during backup (depending on transport In case of automatic selection, source Data Mover could be started on a remote server and read data from the NAS over a slow link. Is there a fix to this or something I need to check? I resolved the problem by changing OS on backup repository server from Windows server 2003 SP2 to Windows Server 2008 R2 SP1. Now sustained backup speed on large VMs are constant and limited only by network speed, in my case link speed 1 Gbps, backup speed ~120 MB/s In my case, changing from off-host to on-host with the backup job configuration on the Veeam server as well as updating all the VM config versions from 5. Top. Really, at that speed?! And in another thread a veeam Setting throttling (via a Network Traffic Rule on the server) to 50Mb/s fixed the unresponsiveness problem. If I copy paste the bvk from local to target repo the speed goes to 100MB/s. I remember having this issue previously on my old Veeam server but that server is since dead and I cannot go back to view the old settings.

I've open a case with Veeam teachnical support as well yesterday In example, the following screenshot shows a full backup for a given virtual machine which runs at about 130-170MB/s: The subsequent (so it is incremental) backup however seems to be much slower with only 15-35MB/s: It was the same with VBR5. And whats the bandwidth from the NAS to the backup server? Is it is CIFS and a low bandwidth, you will get very slow synthentic full speeds.

In addition to using more CPU/Memory that needs to be accounted for on the VM/Veeam itself, your per-object transfer speed is also reduced. Alan, just my 2 cents: Veeam Backup also uses deduplication and compression on the backup files it creates, and that reduces for sure the native speed of any storage it uses, since it has to compare data for the deduplication process, and it Any thoughts? The VM is on 4 VHD files on D and E, which are the slow ones. My setup is as follows: Linux repository with 10GB networking; VMware hosts with 10GB networking; Veeam B&R server with 1GB networking (for job management only) When you run your backup job with throtlling and get low speeds, if you look at your backup job statistics (double-click the job), there are 4 metrics Veeam determines latency on: Source (source storage containing the data Hi, I have downloaded a trial of Veeam Office 365 backup after hearing how good it was in several places as we currently use another product but it's not the best in terms of features.

Copy jobs to SMB StoreOnce repo are very slow (~4 - 5 MB/s), NFS repo to the same StoreOnce works at the normal speed we would be getting Main reason of having source as an explicit bottleneck is the transport mode. I now easily peak around 350-360 MB/s for a single VM backup, where previously it was rather around 200-220 like mentioned in the initial post here, without doing anything else. If i run a backup job at the DR site , i get directSAN speeds when using the local dr veeam proxy, however when a replication is running its always NBD using the proxy at the local dr site Veeam guide mentions that replication is via DirectSAN for the first full backup and for incrementals its always NBD. all the recommendation around suggesting going to the direct SAN access will get the best performance in terms of backup speed. 0) However when we do a VCB backup with the command line, then this customer gets nice and proper speeds.
