Dell EMC Avamar

This software is well suited for companies that want to be very in control of their backups but need a simple tool. It could be convenient for them to just buy their own node, locate it in a different location, and set up the jobs for their machines to backup to the cloud with the specific plugins. However, it would not be convenient for companies looking to have a tool that needs to be secure and compliant, and that need to have different other options for business continuity.

EMC Isilon Scale-Out NAS

EMC Isilon Scale-Out NAS is well suited for larger files (greater the 128 Kb) and where you need to have everything in one common name space. Where it is less appropriate is for many small files (millions of files less than 128 Kb in size) - this causes the protection level to becoming mirroring, which will cost more space.

Pros

Dell EMC Avamar

  • Avamar performs data deduplication on the remote host. This greatly reduces the amount of traffic that each backup requires. This even applies to the virtual environment through change block tracking. Backup times are reduced from hours to minutes.
  • The management interface makes it easy to configure and maintain data retention periods. Many times certain data must be kept for an extended period of time. There is a specific menu for managing retention periods.
  • The system is able to recover itself from a hard failure with virtually no loss of backups. There is a checkpoint taken each day that provides a recovery point in the event of a catastrophic failure. Since this is a node based system, the loss of more than one node could require a recovery be performed.
  • While another grid must be purchased, the replication utility allows all backups to be replicated to another grid at a remote location. This ensures the resilience of the backups in the event there is the loss of the primary data center.
  • Also works on HCI devices performing image-level backups as in our primary data center environment
  • There is also now an All-in-One appliance for smaller locations

EMC Isilon Scale-Out NAS

  • Isilon NAS scales up well and node replacement is easy. You can replace a node by simply adding a new node and evacuating the node that you want to retire.
  • If the file system layout is designed and executed properly it is an excellent SMB platform with the flexibility to adjust to different share structures. Make sure to take the time to fully understand the AD integration and best practices for share and NTFS permissions management.
  • Node redundancy allows for most upgrades to be installed and applied with rolling node reboots allowing the file systems to stay available throughout the process of applying updates.
  • Native replication is excellent. Jobs complete quickly and we rarely have any replication issues with our Isilon to Isilon replication.

Cons

Dell EMC Avamar

  • The client interface has constant JAVA issues and can be slow and chunky. We have often had issues with current versions of JAVA breaking it so it will not even run.
  • The backup clients are split out for function. Although this makes them light, it also makes it cumbersome to upgrade clients. The naming scheme can also be confusing for the clients.

EMC Isilon Scale-Out NAS

  • OneFS block size is somewhere around 128kb stripe unit while most of our tif image files are around 50kb so our logical vs. physical storage is far apart. This caused extra capacity to be needed. I'd like to see the minimum block size to be smaller or initially adjustable depending on user data type.
  • This may just be a training issue, but it's confusing looking at "free" space available when I have a file share mapped to Windows vs. what OneFS states for available free space as they do not match.
  • We noticed that after adding a new node to an existing cluster in production that we had to adjust the networking config in OneFS to allow for another dhcp address so the new node could get an IP address. Normally this wouldn't matter, but it did have a nasty side effect where the SMB service failed after changing the network config which caused a system wide outage since we mostly use SMB protocol. Once the SMB service was restarted via ssh, we were back in business and it was working again.

I have been using the product for over five years. This has performed so well that with the current system reaching its End-of-Life with EMC next year, I have proposed replacing it with the latest version of the product. Now that it integrates with Data Domain, the cost has been greatly reduced. Instead of the need to purchase many nodes, one Data Domain can replace them creating a significant cost savings.

The system overall is easy to monitor and see your backup/restore status. The user interface could use updating as it relies on Java and any updates to Java cause the interface to stop working need to be reinstalled

Support is very convincing, always eager to solve issues from the root rather than workaround, don't hesitate to take webex, describe the issues to the core and recommend configuration to avoid further issues. We can ask few questions other than the main issue. They don't hesitate to answer.

Alternatives Considered

Dell EMC Avamar

Avamar has simplied the back up approach in their VE edition and is much easier to use than Data Protector. Backing up multiple VMs takes minutes instead of hours now. Creating policies, retentions, and schedules, is vastly improved and much easier.

Isilon is immensely more scalable than Celerra and gave us better control over snapshots and replication. The addition of global deduplication provides a huge space savings benefit as well.

Return on Investment

Dell EMC Avamar

  • Avamar served our organization very well for many years. It was absolutely the best solution of its day.
  • We did the fork-lift upgrade twice to continue with Avamar. We could not continue to support this model of upgrades.
  • Our final decision to replace Avamar was when the nodes filled with meta-data while we had plenty of data domain space for backups.
  • We've spent too much engineer time babysitting the product.

EMC Isilon Scale-Out NAS

  • Isilon provides very high value for money
  • Matches the performance and storage requirements of the arrays
  • EMC provides very skillful and high response team in case of any issues in isilon
