Backing up and archiving ONTAP NAS volumes using the Network Data Management Protocol (NDMP) is inefficient, complex and time-consuming.
With NetApp Cloud Backup for ONTAP you can simplify backup operations, run both with more agility and more reliability. How do we save you all that time and money? NetApp’s Cloud Backup Service.
- backs up data at least 10 times faster than traditional solutions
- consumes 97% less network bandwidth
- takes 10 minutes or less to deploy
Here’s a deeper look into the how this quantum leap in backup efficiency is achieved.
Backing up unchanged data is time consuming and wasteful
The amount of data that needs to be copied and moved from the data source to the backup destination varies significantly depending on the type of backup.
- Full backups copy all the files in the volume
- File-level incremental backups copy files that changed since they were last backup up
- Block-level incremental backups copy only the data blocks that changed
NetApp Cloud Backup is block-level incremental. This provides several advantages over traditional NDMP-based backup solutions that perform file-level incremental backups.
- Less stress on production – It only sends blocks that have changed and not entire files removing unnecessary operations from storage and network resources.
- Less failures – File-level solutions cannot backup a file if it’s in use. Cloud Backup uses ONTAP SnapMirror, and it can access and backup the data even if the file is in use.
- Faster scanning – File-based solutions need to scan all the files to determine which ones need to be backed up. This is a time-consuming process, especially for large datasets. Cloud Backup uses NetApp’s lightning-fast Snapshot technology to instantly determine the changes blocks that need to be backed up.
Periodic full backups increase the risk of missing a backup
Traditional NDMP-based backup solutions can only perform up to 9 consecutive incremental backups, after which they need to perform a full backup. Typically, these systems are configured to perform 5 daily backups followed by a full backup over the weekend.
Another unique advantage of using NetApp Cloud Backup is that after the one-time initial full backup, subsequent backups are incremental forever. This drastically minimizes the overall amount of data that needs to be transferred, contributing to its unmatched efficiency.
When there’s no need for periodic full backups, operations become much more efficient and the there is less chance of missing a backup window.
Mediators add overhead and complexity
Another operational advantage is that Cloud Backup backs up and restores directly from source to destination while preserving ONTAP storage efficiencies end-to-end. This is not the case for traditional backup solutions which require a media server in between the source and destination.
NDMP-based solutions first transfer data from the backup source to the media server in its raw format without storage efficiencies (deduplication and compression). Then it is moved from the media server to the backup destination. This time with storage efficiencies.
NetApp Cloud Backup moves data directly from the ONTAP source to the object storage destination while preserving ONTAP storage efficiencies.
The direct backup from source to destination reduces network traffic to less than half compared to traditional solutions. This also removes the complexity of sizing and operating additional infrastructure components.
NDMP backup vs. Cloud Backup
To give an idea of the how all the above advantages translate into operational efficiency, here’s a comparison of a traditional NDMP backup solution with Cloud Backup.NDMP backup vs. Cloud Backup
Let’s take 100TB of ONTAP NAS data that needs to be backed up daily.
We’ll make some rough assumptions for simplicity:
- 5% of the files change per day (20% of the file data changes).
- Deduplication and compression reduce the data footprint by 30%.
Over the weekend, there is a full backup, which moves 100TB from the source to the media server and then 70TB (deduped and compressed) from the media server to the destination. For the daily backups, the traditional NDMP solution moves 5TB (5% of 100TB) to the media server, and then 3.5TB (5TB with 30% deduped and compressed) to the backup destination.
The total backup traffic a week for traditional backup is (5TB+3.5TB) x 5 + 100TB + 70TB = 212.5TB.
NetApp Cloud Backup moves 0.7TB (20% of 5% of the 100TB with 30% deduped and compressed) a day from the ONTAP source to the backup destination.
The total traffic per week is 4.9TB (0.7TB x 7).
Traditional backup sends 212.5TB traffic over the network in a week, compared to 4.9TB sent by NetApp Cloud Backup.
In this scenario, Cloud Backup consumes 96.7% less network bandwidth than a traditional NDMP backup solution.
Data is backed up significantly faster with less risk of failure and less chance of network congestion that could interfere with production traffic.
Hybrid multicloud flexibility
NetApp Cloud Backup is the native ONTAP backup service that lets you backup and restore data anywhere across the hybrid multicloud.
- Backup Source: ONTAP on-premises or Cloud Volumes ONTAP on AWS, Azure or GCP
- Backup Destination: Amazon S3, Azure Blob, Google Cloud Storage or NetApp StorageGRID
- Restore Destination: ONTAP on-premises or Cloud Volumes ONTAP (data can be restored to a location different from the source)
Note: Supported on ONTAP 9.7P5 and above.
It’s time to move away from complex heterogeneous inefficient backup operations. Modernize your ONTAP data protection operations with the NetApp Cloud Backup Service.
