Comparison of Cache Warming and Folder Synchronization Features


Smart Cache has two different features for downloading the files from the Cloud to the on-prem disk for accessing the data faster. These features provide different levels of functionality, and customers can use them based on their use case. The table below gives a glimpse of both these features in a side-by-side comparison.


Do you need it? Folder Synchronization (aka Remote folders) Cache Warming
Folders and their files are downloaded to the local disk for faster access Yes Yes
Individual folder or subfolder selection Yes Yes
Files downloaded by file extension criteria

No (All files are selected)

Yes (e.g., .docx, .pdf, etc)

Files downloaded by minimum file size criteria

No (No file size criteria)

Yes (e.g., file size => 10MB)

Can users access the folder while an operation is in progress?


(Not until it completes full download)


(File can be accessed even when cache warming is in progress.)

Data sprawl issue Yes No
Auto eviction based on last accessed files

(Default 14 days or Custom persistence policies can be set on each device.)

Is manual intervention required by the IT admin if a new folder gets added in the Cloud or obsolete folders need to be removed?


(Local disk storage space gets filled with unwanted data if not monitored regularly.)


(Not required as data lives only for a short time.)
