Use the Advanced tab to change advanced and lesser-used options. Some of these options can cause access or data loss if used improperly, so be careful when making changes in this tab.
Upload
Upload Window and Bandwidth
Use this option to limit the upload bandwidth available to this share according to a user-created schedule for this device. For more information on setting a bandwidth schedule, please see the following article:
How do I limit upload/prefetch bandwidth?
Upload after other shares...
If enabled, this lowers the share's priority on upload. Shares with higher priority will be synced with the cloud first, and lower priority shares will only sync when there are no requests from higher priority shares in the queue.
For more information on share priority, please see the Share Priority section of the following article:
Lock exclusion in Posix ERE
Customers can use this option to disable lock generation for specified types of files by filling in Posix ERE.
Sync Temporary Locks
To improve performance, some lock files are not synced to the cloud by default. Enable this option to include those files in the syncing process.
Sync exclusion in Posix ERE
By default, Morro Data devices exclude certain temporary files from sync. To customize which files are uploaded, enable this feature and add a new Posix ERE. To create a Posix ERE, use the Sync Exclusion List generator by clicking the "Edit" button. For more information, please see the following article:
Please note that we exclude *.bak, *.tmp, etc., if there are many of them on the device, those files will occupy disk space permanently. (If files are uploaded to the cloud, then we can make those files stub files, which do not occupy disk space.)

Prefetch
Prefetch Window and Bandwidth
Use this option to limit the prefetch bandwidth available to this share according to a user-created schedule for this device. For more information on setting a bandwidth schedule, please see the following article:
How do I limit upload/prefetch bandwidth?
Only prefetch specific files by file size
Use this option to limit the file size to prefetch. Customers can set minimum and maximum sizes, only files whose size matches the range will be fetched. This control affects both normal file sync operations as well as manual prefetch operations from MCM.
Only prefetch specific files by file type
Use this option to limit the file type to prefetch by filling a Posix ERE. To create a Posix ERE, use the Sync Exclusion List generator by clicking the "Edit" button. This control affects both normal file sync operations as well as manual prefetch operations from MCM.
SMB
Don't use ea to save streams
This turns off the xattr setting in Samba which can improve file performance. Removing xattr disables extended attribute settings which may affect features such as Windows ACL. This is generally not needed.
Force SMB encrypt
Force encryption to be used for SMB access.
Prevent folder rename when used (slower)
Prevents users from renaming folders if another user has an open file in the folder or a sub-folder. This results in a folder lock.
Disable oplocks
Oplocks allow a client to download and cache a file on its hard drive while making changes; if a second client wants to access the file, the first client receives a break and must synchronize the file back to the server. This can give significant performance gains in some cases. Some programs insist on synchronizing the contents of the entire file back to the server for a single change.
Hide share from browsing
This option prevents a share from being discovered by browsing in Explorer or Finder. Users with access permissions can still access the share.
Allow users to recover own file using shadow copy interface
This option allows users to use the shadow copy interface of Windows to recover versions of a file. After enabling this option for a share, right-click a file and select Properties - Previous versions, you can see the previous versions of the file, select the version you want to recover and use the Restore button to recover.
Please note that there are some limitations:
- Versions must be in the same parent folder and have the same names, the renamed/moved versions will not be listed in the Previous Versions panel.
- This option doesn't support folders currently.
- This option doesn't support stub files currently.
- Only the last 100 versions can be listed on the Previous Versions panel.
- Recovering an old version will replace the current version.
- When recovering a version, there is no size limitation for the version for now. Recovering a very large file (10GB for example) may have problems.
- We use temporary directories in CacheDrive to store old versions of a file when the user views the Previous Versions panel of the file, so users may see these paths in some applications (such as "Recent" page of Word).
- The temporary directories will be deleted 2 hours later after the user opens the Previous Versions panel, so if the user keeps the Previous Versions panel open for a long time, the user may see the below error with garbled code when trying to restore a version.
NOTE: There are some account optimization/tuning options in Account Options.
RTC
Use this tab to enable/disable Remote Team Collaboration features for the share.
For more information on the file types affected by each RTC slider, please see the following article:
Which file extensions does each RTC type support?
ECHO
Select an account that was created from MCM - Apps - Dropbox ECHO or OneDrive ECHO, and select a CacheDrive as a master gateway to enable ECHO for a share. Master gateway will be used to sync files with Dropbox or OneDrive.
Transfer
Use this tab to enable the performance option to have simultaneous upload and download when syncing large files.
