* To perform daily backup using cron and to load environment configuration with a "cron-primer" file: * To perform daily backup using cron and to load environment configuration with a "cron-primer" file:
- `0 0 * * 0 ec2-user /home/ec2-user/ec2-automate-backup.sh -c /home/ec2-user/cron-primer.sh -s tag -t "Backup=True"` - `0 0 * * 0 ec2-user /home/ec2-user/ec2-automate-backup.sh -c /home/ec2-user/cron-primer.sh -s tag -t "Backup=True"`
`-a` - the -a flag will tag snapshots with additional data so that snapshots can be more easily located. Currently the two auto tags created are Volume="ebs_volume" and Created="date" `-u` - the -u flag will tag snapshots with additional data so that snapshots can be more easily located. Currently the two user tags created are Volume="ebs_volume" and Created="date." These can be easily modified in code.
