Use the "Manage Caching" option to pull files, folders, or share into the cache or to clear up cache space.


With this option, at a time, you can manage caching for one share, multiple folders, multiple folders and files, or multiple files.



Manage Caching for Share or Folder


If you select a share, one or more folders, or folders and files together, the below dialog will appear when you click the "Manage Caching" button. Select the gateway you wish to manage from the dropdown and click "Check". 



Then you can view the "Cache Size", "Unused Cache Space" and "Writable Cache Space" of the gateway. Then you can decide the next operation:

  • Cache Out - Click this button to remove the contents of your selected files, or files in your selected share/folders from the cache. But the metadata of the files will still be kept in the gateway.
  • Fetch - Click "Fetch" will jump to the Fetch page, there are two options on the Fetch page: "Force prefetch" and "Fetch by Timestamp" (the Fetch page with these two options will be introduced later). Enable or disable these two options according to your needs, then click the OK button to pull the contents of your selected files or files in your selected share/folders from the cloud to the gateway. Files that have already been cached will not be fetched again.



Manage Caching for File

If you select only files, the below dialog will appear when you click the Manage Caching button. Select the gateway you wish to manage from the dropdown and click Check.



Then you can view the status of files, cloud icon means the content of the file is not in the cache (Cached-out), and the file icon with a check mark means the content of the file is in the cache (Cached-in).


You can select all files in the list by cache status using the Filter by radio buttons.


For cached-in files, you can click the "Cache Out" button to remove the contents of your selected files from the cache. But the metadata of the files will still be kept in the gateway. 


For cached-out files, you can click the Fetch button, then the page will jump to the Fetch page. There are two options on the Fetch page: "Force prefetch" and "Fetch by Timestamp" (the Fetch page with these two options will be introduced later). Enable or disable these two options according to your needs, then click the OK button to fetch the contents of your selected files from the cloud to the gateway.



Fetch page - Fetch by Timestamp

"Fetch by Timestamp" is off by default. Enable this option to prefetch only files modified after the selected time.




Fetch page - Force prefetch

"Force prefetch" is on by default. Enable this option when manually fetch files will ignore the conditional prefetch rules.

  • Conditional prefetch rules for automatic prefet ("Only prefetch specific files by file size" and "Only prefetch specific files by file type") can be set in "File System > Share Advanced > Prefetch". Please refer to Manage Share - Advanced.
  • Force prefetch will still follow the Fetch by Timestamp setting.

If disable "Force prefetch", then only files that meet the conditional prefetch rules will be prefetched.



Note: "Fetch by Timestamp" is not limited by "Force prefetch". When "Fetch by Timestamp" and "Force prefetch" are both enabled, only files that were modified after the selected time in "Fetch by Timestamp" will be fetched. 



Fetch Status

You can find the status of the fetch on the Devices page  MCM.




Limitations

  • Only one share can be selected at a time. 
  • Up to 150 files and folders can be selected at a time.
