# Take a snapshot of an existing droplet
# The syntax is: snapshot Droplet_ID Snapshot_Name
# For example to take a snapshot of droplet with ID "72100":
#snapshot 72100 domain.com

# Vertical Scaling - Increase RAM, CPU, Disk
# The syntax is: resize Droplet_ID New_Size_ID
# For example to resize a 512MB droplet to a 1GB droplet with ID "72100":
#resize 72100 63

# Horizontal Scaling - Clone a server from a snapshot
# The syntax is: spinup Droplet_Name Size_ID Image_ID Region_ID
# For example, to spinup a 512MB clone of domain.com webserver with image ID "12573" in New York datacenter (Region 1):
#spinup domain.com 66 12574 1
