Hey Guys,
I am recently experiencing a performance issue with Arcserve R 15.0 on vSphere 4.1 using VDDK. Without any documented change to our backup environment certain VM Guests have slowed down to 300mb/min on backing up from our FC SAN.
Ive ensured they are no previous snapshots and that other vm guests on the same datastore backup as expected. I have also verified other vm guests on the same hosts as the troubled guests backup as expected, and I looked inside the guest's os at the fragmentation on the drives and everything looks normal.
I have all the necessary logging turned on in Arcserve and do not see anything really unusually. I have verified the VMDatastoreTypes.ini file has the SAN setting of 0 for the problem vm's.
Can anyone shed some light on this issue or point me in the right direction?
thanks
