i'm facing a slowness in VM backup,mentioned that in past the full vm backup finished for (560 Gb) finished within 2 hours,but now the backup take more than 18 hours.
i'm using (nbd) transport type,backup taking to symantec appliance,i tried to add another vm machine in same host under the vcenter and backup finished fast
Need your advise.
Vshpere version is : 5.5
Netbackup version : 22.214.171.124
Applicance version : 2.6.3

One thing that can slow backups down is fragmented disks, if you have a lot map disk region entries in the vcenter events it indicates that your vmdk(s) is fragmented. As a vmware backup is actually a flashbackup, it might also be worth defragment the file systems inside the VM.
Other than this I would look in vsphere performance monitor to see if there was something that indicated a problem on the VM or the underlying infrastructure
Are the new VM also on the same datastore ?
appliance in environment... why not adopt SAN transport... it would be worth time savings and other too. while backups are shifted to SAN....
is it possible moving vm (vmotion) to another esx and check backups..... also if VM instance is clustered... try with another VM for same application / DB....
just confirming VM is given storage from datastore only..(and hopefully doesn't have snapshots on it...)
If its from iSCSI try checking on same.
That sounds strange, as you then backup more data than before.
Curious have you disabled all at once or one thing at time ?
