Backup and Restore Petabyte-scale Data Volumes

large nas backup and restore

Do you have billions of files sitting on scale-out NAS such as NetApp, Dell/EMC Isilon or StorNext or Qumulo? Or are you using Lustre or GPFS shared file system from vendors like DDN GRIDScaler and IBM Spectrum Storage? Are your NDMP solutions hitting their upper limits as you reach or head towards petabyte levels? Are you looking for a powerful and reliable solution to protect your massive unstructured data sets?

Atempo delivers powerful, vendor-agnostic backup/restore solutions for petascale NAS environments.


Protect petabyte Storage Platforms and NAS



Daily changes on large volumes of hundreds of millions or even billions of small files means that scanning a scale-out NAS for changes can be a long and painful wait.

Atempo leverages a mix of its proprietary FastScan Technology and the SnapShot feature available on most NAS and shared or parallel file systems to quickly collect the list of changed & new files. This ensures rapid data backup movement.


incremental forever backups

Incremental Forever

The standard backup approach that requires doing cycles of Full and Incremental backups does not work with petascale storage. Petascale volumes required a radical rethink to end subsequent Full backups.

Atempo's response is to deploy an "Incremental Forever" approach with the smart management of data versioning at backup target levels. We create considerable backup time and backup storage savings.

optimized recovery

Optimized reCOVERY

Built-in support of Atempo's Time Navigation technology makes retrieval of backed-up data from any selected moment extremely easy and efficient. If you just need to recover a few files, simply drag and drop from target to source.

To rebuild a full volume or a complete storage infrastructure, Atempo has fully automated large volume DR capability. Prioritize which folders/volumes to recover based on your business needs.

speed scalability and security


Atempo customers often handle extremely large files in addition to hundreds of millions of small files which transit between petabyte storage.

Large data sets are transferred by scalable farms of Atempo Data Movers, which can each move several GB/s in an highly parallelized and multi-threaded environment. A whole data-moving farm will deliver more throughput than most networks can handle.

To increase performance, simply add a Data Mover. Scalability is no longer a concern.

Cross storage platform restore


What happens in the event of a serious incident and a full-blown DR situation? Atempo's NAS-agnostic solutions help you weather the storm.

  1. While waiting for your petabyte storage replacement, you can restore any critical data to other available target storage available (with full ACLs preservation)
  2. When the new storage is available, organize and prioritize data restore based on a business unit, a user group, a volume. Whatever you need for your business.

Rebuilding your petascale NAS/GPFS storage is no longer a burden.

wide choice storage destination and targets

WIDE Storage TARGET Choice

Disk, object storage, optical disk, tape, cloud storage media, including combinations of these, can be based on one or more storage technology.

Because backup must respect both budget and performance, Atempo offers a broad storage compatibility list with deep integration guaranteeing optimal performance.



 "I wanted life insurance for my critical data. Atempo-Digital Archive has given us this."

We have backed up our unstructured NAS data sets based on multi-OS sources while respecting ACLs. Thanks to Atempo, we have NFS and CIFS file systems working in perfect harmony with S3-type storage”.
