BEAR DataShare FAQ

 

Welcome to the Bear DataShare FAQ portal, find answers to those unanswered questions, however if we've not added it here then please let us know by sending us a 'ServiceDesk' request via http://itservicedesk.bham.ac.uk.

 Folders are not fully synchronized

Problem

Sometimes it may occur that folders doesn't reach the 100% synchronization mark, means synchronization doesn't finish and the folder stays in an unsynchronized condition.

There are three possible reasons:

  • transfer mode has been configured which doesn't allow automatic synchronization.
  • Files within a folder with that problem are permanently in use by other programs and therefore block access to those files by the client.
  • The internal folder database has been damaged.

Solution

There are two possible solutions:

  • Check for files which have not been synchronized: Click on Show Folders and then click on the folder which are not fully synchronized. From the internal file browser, which should have opened up to the right of the client user interface, select Unsynchronized files from the filtering drop-down selection and also enable the Flat View check-box. Now you should see a list of all files which have not been synchronized yet. Please check if those files are in use by any other program.
  • Check if the transfer mode for the folder has been set to anything else than Auto SyncEnable Expert Mode. Click on Show Folders and then click on the folder which are not fully synchronized. Click on the Settings tab in the panel, which should have opened up to the right of the client user interface, and check if the transfer mode is NOT set to Auto Sync.

 Drag and Drop using web portal

Problem

When using the web portal, users are unable to drag and drop whole folders, only files withinthe folders are uploaded

Solution

The complete upload of a folder including contents is not supported, so drag and drop only works for single files only, this is not a so much a decision by the supplier but more a restriction from the browser.

To overcome this issue, while browsers implement the api, is to either use the client or zip the file up and upload via the web portal.

 Restoring deleted files

Problem

Files have been deleted by mistake and need to be recovered

Solution : Using the web client

  1. Click on Folders
  2. Click on the folder which contains the deleted file and browse through the directory structure to the sub-directory where the file was originally located.
  3. Click on the Show deleted files icon ( clock with arrow going anit-clockwise )
  4. Now you should see a list of non-deleted and deleted files. Locate the deleted file and click on the restore icon ( green circular arrow going anti-clockwise ).
  5. The file should now be available again.  If you have the client installed on your device the restore will be propogated when you synch with this folder.

Solution : Using the desktop Client

Please follow the user guide section entitiled 'Restore a Previous Version'. The user guide guide can be found on the 

 Illegal characters

 Problem

This problem indicates that there are files with names containing illegal characters. Different operating systems have different sets of characters that are legal for file names.

On Windows systems the following characters are not permitted as file name characters:

  • |
  • \
  •  ?
  • *
  • <
  • "
  • :
  • >
  • /

On Linux systems the following characters are not permitted as file name characters:

  • /

On Apple systems the following characters are not permitted as file name characters:

  • /
  • :

Since the client may synchronize data to a number of devices, this may become an issue in the future if the folder is joined on a device where these characters are a problem.

Solution

When this notification appears in the client, you can select a new, safe name for the file and rename it.

 Illegal end characters

Problem

This notification indicates that there are files with names ending in characters that are illegal on Windows systems. The characters are dot (.) and space ( ). For example there may be a file named 'Test.txt ' or 'test.txt.'.

Since the client may synchronize data to a number of devices, this may become an issue in the future if the folder is joined on a device running Windows.

Solution

When this notification appears in the client, you can select a new, safe name for the file and rename it.

 File name too long

Problem

This notification indicates that there are files with the names longer than 255 characters. Files with names longer than this can cause problems on some operating systems.

Since the client may synchronize data to a number of devices, this may become an issue in the future if the folder is joined on a device where very long file names are a problem.

Solution

When this notification appears in the client, you can select a new, shorter name for the file and rename it.

 Duplicate filenames

Problem

This notification indicates that there are files with the same file name, but with different case. For example there may be a file named 'Test.txt' and another named 'test.txt'.

While this may be acceptable on some operating systems, it may not be on others. Since the client may synchronize data to a number of devices, this may become an issue in the future if the folder is joined by a device where duplicate names are not permitted.

Solution

When this notification appears in the client, you can select a new, unique name for the file and rename it.

 Reserved words in filenames

Problem

This notification indicates that there are files with names that are reserved words on Windows systems. Reserved words include:

  • CON
  • LPT1
  • NUL

While these may be acceptable on some operating systems, they may cause problems on Windows systems. Since the client may synchronize data to a number of devices, this may become an issue in the future if the folder is joined on a device running Windows.

Solution

When this notification appears in the client, you can select a new, safe name for the file and rename it.

 Client deletes files

Problem

Files are disappearing without any obvious reason, they seem to be deleted.

The client itself doesn't delete files on his own, therefore the most likely reason is that the files were deleted by an other member of the folder on an other device.

Solution

The client moves deleted files into its internal file archive by default, so the files are actually not deleted.

When displaying only deleted files in the internal file browser of the client, you can also see from which machine or from which user the file was last changed (deleted), so you can check why it was deleted there.

As soon as you restore a file or multiple files from the archive those changes will be propagated to other clients as well, so the file(s) will be available on all devices again. If the files were backed up online, they can be restored using cloud web interface as well.

 Where are the BEAR DataShare application servers

The solution has been created to be highly resilient and is hosted in two data centres on campus. If there is a major issue at one data centre, the service will continue to operate from the other.  Most predictable failure scenarios have been addressed, notably:

  • Single disk failures
  • Enclosure failures
  • Inter-site link failure
  • Site (single Data Centre) failure
