Deploying secure backup on to the Cloud

  1. 1. How do weDeploy a secure backup to the CloudLahav Savir,
  2. 2. Lahav Savir• 15 years in on-line industry• Architect and CEO @ Emind Systems (est. 2006)• AWS solution provider• Over 30 AWS customersHobbies (that’s the . . .)• MTB cycling• Mountain hiking
  3. 3. Backup scenariosOn premises to off-site On the cloud to other site• File servers • File servers• Backup files • Large data volumes• Data base dumps • Data base dumps archiving • Large S3 buckets• Disaster recovery
  4. 4. Storage scenariosStorage appliances Disks & Servers• NFS • Windows shares• CIFS • Linux exports • Linux servers • Sun exports
  5. 5. RequirementsBackup• Keep a replica of the data off-site• Keep history of the data for X previous months• Secure transfer• Encryption of data sets• Large files• Delta transferDeployment• Don’t impact existing setup• Don’t install any SW on servers• No additional hardware
  6. 6. Few more . . .• Control bandwidth throughput• Visibility and monitoring• Simplicity• Keep the costs down – License – Traffic – Storage
  7. 7. Alternatives• Windows • Storage built-in – Virtual drive to S3 integration tos3 – Sync application – No monitoring – Cygwin / delta copy – No visibility to status – No bandwidth control• Linux – No feedback – s3fs (fuse) – s3cmd
  8. 8. Simple solution• Sync Manager – Linux appliance – cifs-utils – rsync – s3cmd – tc (traffic controller) – net-snmp – curl
  9. 9. Sync Configuration• rsync (filer to filer)rsync;/filer/data1/; sync@{A}rsync;/filer/data2/; sync@porticor_vpd:/data2• s3 (filer to s3 with / without VPD)s3;/var/www/wordpress/;s3://bucket1/wordpress-{d}/;--no-delete-removeds3;/mnt/srv1/;s3://bucket2/
  10. 10. Bandwidth control• Tag user trafficiptables -t mangle -A OUTPUT -m owner --uid-owner $SYNCMGR_UID -j MARK--set-mark 0x1• Create root qdisc for eth0$TC qdisc add dev $IF root handle 1: htb default 30• Add a class (bucket) with bandwidth restrictions$TC class add dev $IF parent 1: classid 1:2 htb rate $MAXRATE• Then add a filter to force packets through the class$TC filter add dev $IF protocol ip parent 1:0 prio 1 handle 1 fwclassid 1:2Tip: use iftop to see it in action
  11. 11.

  12. 12. Cloud backup hosts• ec2 instance (Linux server) – EBS volumes• s3 buckets• Porticor VPB – EBS volumes – S3 proxy
  13. 13. Hosting on the cloud• Public cloud – Instance behind security groups with SSH keys• VPC – Instance behind VPN • AWS VPN Gateway • IPSec with CheckPoint in the VPC • IPSec with Swan in the VPC • SSL VPN with OpenVPN in the VPC
  14. 14. Restoring• rsync back from storagersync ; sync@{A} ; /filer/data1/• 3scmds3cmd get s3://bucket2/file /path/to/restore/file
  15. 15. Summary• Simple and open solution• No impact on customer infrastructure• No additional HW required• Control with full visibility• Fully integrated with NMS• Reliable• Secure
  16. 16. AWS Tips• Don’t forget to set AWS console to MFA• Setup a VPN to your AWS server• No public SSH• Monitor traffic coming into your servers• Multi-region / AZ for high availability• Use ec2 tools• Backup backup backup . . .
