Backing Up Amazon EFS — https://docs.aws.amazon.com/efs/latest/ug/efs-backup-solutions.html
第3種方式,非官方建議, 但有相當程度的便利性
EFS ↔ EC2/EBS ↔ EBS snapshot ↔ S3
先用台EC2透過rsync + parallel去備份EFS上的資料，再透過EBS snapshot的方式備份資料到S3,達到定期多版本的備份策略!
### rsync + parallel
$ cd /usr; time find -L -type f | sudo parallel — gnu -j 8 -v rsync -aR {} /shared/b### backup
NOW=$(date +”%Y-%m-%d-%H-%M-%S”)
echo $NOW$ aws ec2 create-snapshot — volume-id vol-1234567890abcdef0 — description “Auto-backup-”$NOW — region
