hvSnapshotLifeTimeHour Reg Key location

Veeam Logoby cmbc » Sat Mar 21, 2015 10:06 am

Hello,

i'm having issue with big VM to backup on slow hardware. I have read that a new option now exist to customize the TTL of snapshot.
http://www.veeam.com/kb1854
Code: Select all
Maximum volume snapshot life time is now customizable using the hvSnapshotLifeTimeHour (DWORD) registry value. Default value is 72 hours, but customization may be necessary to allow full backup of very large VMs on slow backup hardware.


Bug where do you place this REG Key?

Thanks for help

It should be configured on the backup server > HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication\

I'm not sure, but I would recommend to double this value as 144 hours should be sufficient to cover the backup window.

Do I have to restart the veeam services after applying this reg setting? I am asking because our backup is currently running, and I know it will take more than 72 hours..

Yes, Veeam backup service should be restarted for the key to take effect.
