Some Files Are Continuously Uploaded to the Server, Even When They Are Not Modified.
|
||
------------------------------------------------------------------------------------
|
||
|
||
It is possible that another program is changing the modification date of the file.
|
||
If the file is uses the ``.eml`` extension, Windows automatically and
|
||
continually changes all files, unless you remove
|
||
``\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\PropertySystem\PropertyHandlers``
|
||
from the windows registry.
|
||

Syncing Stops When Attempting To Sync Deeper Than 100 Sub-directories.
|
||
----------------------------------------------------------------------
|
||
|
||
The sync client has been intentionally limited to sync no deeper than 100
|
||
sub-directories. The hard limit exists to guard against bugs with cycles
|
||
like symbolic link loops.
|
||
When a deeply nested directory is excluded from synchronization it will be
|
||
listed with other ignored files and directories in the "Not synced" tab of
|
||
the "Activity" pane.

I See a Warning Message for Unsupported Versions.
|
||
-------------------------------------------------
|
||
|
||
Keeping software up to date is crucial for file integrity and security – if
|
||
software is outdated, there can be unfixed bugs. That’s why you should always
|
||
upgrade your software when there is a new version.
|
||
|
||
The ownCloud Desktop Client talks to a server, e.g. the ownCloud server – so
|
||
you don’t only have to upgrade your client when there is a new version for it,
|
||
also the server has to be kept up-to-date by your sysadmin.
|
||
|
||
Starting with version 2.5.0, the client will show a warning message if you
|
||
connect to an outdated or unsupported server:
|
||
|
||
.. image:: https://owncloud.org/wp-content/uploads/2018/09/ownCloud-unsupported-version-warning-message.png
|
||
|
||
**Because earlier versions are not maintained anymore, only ownCloud 10.0.0 or
|
||
higher is supported.** So if you encounter such a message, you should ask your
|
||
administrator to upgrade ownCloud to a secure version.
|
||
|
||
An important feature of the ownCloud Client is checksumming – each time you
|
||
download or upload a file, the client and the server both check if the file was
|
||
corrupted during the sync. This way you can be sure that you don’t lose any
|
||
files.
|
||
|
||
There are servers out there which don’t have checksumming implemented on their
|
||
side, or which are not tested by ownCloud’s QA team. They can’t ensure file
|
||
integrity, they have potential security issues, and we can’t guarantee that
|
||
they are compatible with the ownCloud Desktop Client.
|
||
|
||
**We care about your data and want it to be safe.** That’s why you see this warning
|
||
message, so you can evaluate your data security. Don’t worry – you can still
|
||
use the client with an unsupported server, but do so at your own risk.

There Was A Warning About Changes In Synchronized Folders Not Being Tracked Reliably.
|
||
-------------------------------------------------------------------------------------
|
||
|
||
On linux when the synchronized folder contains very many subfolders the
|
||
operating system may not allow for enough inotify watches to monitor the
|
||
changes in all of them.
|
||
|
||
In this case the client will not be able to immediately start the
|
||
synchronization process when a file in one of the unmonitored folders changes.
|
||
Instead, the client will show the warning and manually scan folders for changes
|
||
in a regular interval (two hours by default).
|
||
|
||
This problem can be solved by setting the fs.inotify.max_user_watches
|
||
sysctl to a higher value. This can usually be done either temporarily::
|
||
|
||
echo 524288 > /proc/sys/fs/inotify/max_user_watches
|
||
|
||
or permanently by adjusting ``/etc/sysctl.conf``.

||
I Want To Move My Local Sync Folder
|
||
-----------------------------------
|
||
|
||
The ownCloud desktop client does not provide a way to change the local sync directory.
|
||
However, it can be done, though it is a bit unorthodox.
|
||
Specifically, you have to:
|
||
|
||
1. Remove the existing connection which syncs to the wrong directory
|
||
2. Add a new connection which syncs to the desired directory
|
||
|
||
.. figure:: images/setup/ownCloud-remove_existing_connection.png
|
||
:alt: Remove an existing connection
|
||
|
||
To do so, in the client UI, which you can see above, click the "**Account**" drop-down menu and then click "Remove".
|
||
This will display a "**Confirm Account Removal**" dialog window.
|
||
|
||
.. figure:: images/setup/ownCloud-remove_existing_connection_confirmation_dialog.png
|
||
:alt: Remove existing connection confirmation dialog
|
||
|
||
If you're sure, click "**Remove connection**".
|
||
|
||
Then, click the Account drop-down menu again, and this time click "**Add new**".
|
||
|
||
.. figure:: images/setup/ownCloud-replacement_connection_wizard.png
|
||
:alt: Replacement connection wizard
|
||
|
||
This opens the ownCloud Connection Wizard, which you can see above, *but* with an extra option.
|
||
This option provides the ability to either: keep the existing data (synced by the previous connection) or to start a clean sync (erasing the existing data).
|
||
|
||
.. important::
|
||
|
||
Be careful before choosing the "Start a clean sync" option. The old sync folder *may* contain a considerable amount of data, ranging into the gigabytes or terabytes. If it does, after the client creates the new connection, it will have to download **all** of that information again. Instead, first move or copy the old local sync folder, containing a copy of the existing files, to the new location. Then, when creating the new connection choose "*keep existing data*" instead. The ownCloud client will check the files in the newly-added sync folder and find that they match what is on the server and not need to download anything.
|
||
|
||
Make your choice and click "**Connect...**".
|
||
This will then step you through the Connection Wizard, just as you did when you setup the previous sync connection, but giving you the opportunity to choose a new sync directory.
