Question about DRE cache usage

show stat dre

Cache:

Status: Usable, Oldest Data (age): 4d9h

Total usable disk size: 116735 MB, Used: 95.21%

Does this look normal?  Sould I be concerned?  What should be done to reduce the usage?

Thanks

Question about DRE cache usage

Hi Joe,

Yes, it's perfectly normal to have the DRE cache usage at close to 100%.DRE will fill its partition to the maximum in order to maximize the optimization.

The DRE cache will not overflow the partition size because, old data will be replaced with the more recent one as required. This same command also shows the age of the oldest data object, which gives you an estimation on how fast the DRE cache gets overwritten.

Best regards

Daniel
