<html><body><span style="font-family:Verdana; color:#000000; font-size:10pt;"><div>HI John, all of the backups we have taken were from the 24/7 uptime operational production servers. The 4-5 days duration is taken from these backups. Several months ago we restored one of these backups to another higher capacity database server on fiber channel storage in a different location, then we upgraded postgis from 1.5.8 to 2.1.1 and PostgreSQL from 9.1.6 to 9.3.3, that restore took 9-10 days to finish. We have another VM that has been set aside to be stood up asap as our standby server to this primary. Currently, this standby VM only has Linux 6.4 installed, no PostgreSQL or PostGIS. I was thinking if we can perform a VM clone, we wouldn't have to install PostgreSQL, Postgis, packages, etc., on the standby server.<br></div><div><br></div><div><br></div>
