With Data Protector 8.0 and when a backup for virtual machines, using the “Virtual Environment Integration”, is performed, a message might be displayed “Requested operation timed out”. The message has been seen, when long-running snapshots are created by the Virtual Center server. The timeout occurs after 60 seconds. The root cause is a changed behaviour in DP 8.0 compared to Data Protector 7.0. In the file omnirc the variable VI_API_TIMEOUT can be inserted to increase the value for the timeout. The standard value in Data Protector 7.0 is 300 seconds, for Data Protector 8.0 the standard was decreased to 60 seconds. By inserting the variable with a value of 300 the timeout will be increased, hence the snapshot is done as expected and the backup will run as expected.
Daniel,
In the DP8 i see a strange behavior between VEPA and CBT ( changed block tracking ). After enable it in DP, all the process related to CBT are made ( activate the CBT in VM, messages in the GUI ) but the DP copy of all the content of VMDK. In some cases if i mark the Snapshot handling to Single/MIxed and run a full backup, the CBT works fine, in some cases.
Do you see this behavior in DP8 ? Because in DP7 this works fine with the same process.
Hi Diogo,
I have seen the behaviour you described for DP 7.0 too. The workaround is to use Snaphot handling Single/Mixed and to configure the CBT for each individual virtual machine. At least this waht I have seen for some of my customers.
Best regards
Daniel
