SCPHOST=
LOCALDIR=
TEMPDIR=$(mktemp -d)
DATE=$(date '+%Y%m%d')

### Usage Menu
usage()

cat << EOF

usage: $0 <OPTIONS>

This script will stop, backup, gzip, and send all vms. It assumes the
credentials for any remote server have been configured. More than one
backup location can be supplied.

OPTIONS:
  -h Show this message
  -f <server> FTP host to send backups to. (ex. google.com)
  -s <server> SCP host to send backups to. (ex. google.com:/backups/)
  -l <directory> Directory to store backups locally. (ex. /backups/)

The backups will be stored in the following form:
<alias>-<YEAR><MONTH><DAY>.gz

To restore a gzipped backup, perform the following:
gunzip -c <backup> |vmadm receive

NOTES:
FTP credentials can be stored in ~/.netrc with permissions 600 and
formatted thusly:

machine <fqdn/ip>
	login <username>
	password <password>
