Slow Storage Backups

Why are our storage backups taking so long to complete?


The Problem

An ecommerce retailer was experience rapid growth on their online infrastructure. A storage vendor had convinced this manufacturer that they needed a major refresh to meet the growth of their storage requirements. The greatest point of impact was the database storage infrastructure. The storage administrators knew that storage I/O could have a double impact on application performance since it affects both the storage system directly (the databases), as well as the network via saturation due to excessive transfers. This additional traffic could have a serious, negative impact on performance and in one of the more recent incidents, the backups were taking much longer to complete than usual.

Desired Outcome

  • Quickly discover why the backup jobs are taking longer than previous runs
  • Prevent database and network issues from storage and backup issues

This additional traffic could have a serious, negative impact on performance and in one of the more recent incidents, the backups were taking much longer to complete than usual.


The Solution

The storage administrators had created a dashboard to monitor NFS activity to allow them to easily identify file I/O outside of normal, expected parameters. This let them identify activity that negatively affected their app performance. In the case of the latest backup slowdown, an admin had mistakenly configured full log backups instead of incremental. The dashboard provided real­-time visibility to key data, bytes in & out by file and filer, transaction types by file and request count by file. the additional traffic full full log backups was having a serious, negative impact on performance. The team further refined their dashboards to track and analyze NFS usage irregularities.

User Impact

With ExtraHop the customer was able to save $250,000 in unnecessary storage platform growth, significant effort upgrading network infrastructure and significant app performance degradation.
