Nextcloud will initially move deleted files and folders to “deleted files”.

• Deleted Files: This is where you will find any files you have deleted, which you can restore. You can search for files using the search bar in the top right of the screen. After restoring a file you can click on "…“ –-> "Details" –-> "Activity" to see who deleted the file and when.
•  Activitiy: Here you can see any changes and activities that have been made, with time stamps. If the data you are missing is from a shared document or folder, you can check here if someone changed or deleted it. If the files were simply moved it will be shown here as well.

Please note: When checking the deleted files folder, you will need to check the account of the person the file belongs to or the account that actually deleted the file. This is important when dealing with files from shared folders.

Files that you delete are initially moved to “deleted files”. Nextcloud deletes the oldest files until at least 50% of the available space is free. You can manually delete items completely at any time.

Click on the "…“ next to the file and select "Details“. Go to the tab „Versions“. Click on the downward pointing arrow to download the available versions. You can then decide which version should be restored. To restore the version, click on the circular arrow symbol

Nextcloud keeps difference versions of a file:

• In the first second, a version is created.
• In the first ten seconds, a version is created every two seconds.
• In the first minute, a version is created every ten seconds In the first hour, a version is created every minute.
• In the first 24 hours a version is created every hour.
• In the first 30 days a version is created every day.

As soon as a new version is created the older versions adapt to this scheme. The versions will never use more than 50% of the storage space available.

Your cloud storage can be increased. Please send an email to support@uni-konstanz.de detailing how much space you require and for which acount.

It is currently not possible to increase storage space for students.

A comprehensive guide is available here.

An internal link can only be used by users who have permission to access the file. This means the file or folder needs to have been shared with them previously. Access is only permitted for users who have logged in.

An internal link looks like this: cloud.uni-konstanz.de/index.php/

A public link can be used by anyone without needing to log in. Public links are particularly useful for external users who don’t have a university account (assuming they don’t have their own cloud instance). Access to public links can be protected using a password so that only a select group of people can use them.

A public link looks like this: cloud.uni-konstanz.de/index.php/

Received shares will initially appear at the top level in your cloud storage area. You can always cancel a received share. Received shares can also be moved to your own folders or renamed. This is best done in the web interface. When renaming the share, the name is only changed for you personally. The sharing account will see the original name. However this does not apply to sufolders contained in the folder. If these are renamed, they will be renamed for the owning account as well as other share recipients.

Under personal settings go to the section "Sharing“ (https://cloud.uni-konstanz.de/index.php/settings/user/sharing). Under "Files“ you can select the folder and the new owner.

You can find detailed instructions in the Nextcloud-documentation

Yes, all permissions/shares are also tranferred.

Should you want to receive federated shares, you will need to hand out your Federated-Cloud-ID. This is a combination of your username and cloud.uni-konstanz.de. For example: jane.doe@cloud.uni-konstanz.de. Alternatively you can use your uid (popID) and cloud.uni-konstanz.de, for example: pop123456@cloud.uni-konstanz.de.

If icons or entire sub-menus are missing from the cloud, this could be due to your adblocker. A known issue with the adblocker “Adblock Plus” is that is can block harmless page elements. If this is the case, please uninstall is and replace it with the Mozilla recommended adblocker “uBlock Origin”

The client should issue a notification detailing which error has occured during the synchronisation. You should read this carefully.

Sometimes restarting the synchronisation will help.

By default the sync-client only synchronizes folders that are smaller than 500 MB. If folders are larger, it will ask if they should be synchronized. You will need to confirm this manually or increase the general limit in the client settings.

Nextcloud Documentation

Data conflicts kann occur, particularly in shared folders. As a rule, the sync-client will inform you that you need to resolve the issues yourself, for example by choosing between two file versions, the one saved locally or the one on the server. Alternatively you can rename one of the files manually and then check both versions.

It is possible, that the directory was shared with you twice, each time with different permissions. Once in the directory itself and once in the parent directory containing the child directory. Permissions will vary depnding on how the directory is accessed (directly or indirectly).

The web standards for universal accessibility have been implemented for the cloud. The cloud's web interface is usable via keyboard and is compatible with auxiliary programs such as screen readers. Information on accessibility can be found in the user manual https://docs.nextcloud.com/server/latest/user_manual/de/universal_access.html

The transfer of data to the university cloud is encrypted, however it is stored unencrypted on our internal storage system. Highly sensitive data should therefore be stored in the cloud using end-to-end encryption. Until this is offered as an integrated service by Nextcloud (ETA wintersemester 2023) you can use dedicated software such as Cryptomator VeraCrypt.
For questions regarding the evaluation your data’s protection requirements, please contact the information security team

As soon as an account is deactivated any data in the cloud will be deleted, including data shared from the account! An e-mail will be sent to the account before it is deactivated. It is important that you check your emails regularly to ensure you can either extend the account, transfer the shared folder to another account  or archive the data.

Synchronising the same directory with Nextcloud and other synchronisation software such as Unison, rsync, Microsoft Windows Offline Folders, or other cloud services such as Dropbox or Microsoft SkyDrive is not supported and should not be attempted. In the worst case, it is possible that synchronising folders or files using Nextcloud and other synchronisation software or services can result in data loss.

From the files view (https://cloud.uni-konstanz.de/index.php/apps/files), click on "Settings" in the bottom left corner. You will see a URL for your personal WebDAV connection. It will look like this: https://cloud.uni-konstanz.de/remote.php/dav/files/popXXXX

Alternatively you can use the following address structure should the first option not work: davs://firstname.lastname@cloud.uni-konstany.de/remote.php/webdav

More information is available here

Nextcloudcmd also connects to the cloud via the WebDAV protocoll. However, it does not understand "firstname.lastname“. You will need to use your uid (popXXXXXX) instead. The URL cannot contain a username. The command should look something like this:

"nextcloudcmd /path/to/local/folder https://popXXXXXX@cloud.uni-konstanz.de/ "

The following should also work for a subfolder:

"nextcloudcmd /path/to/local/folder/Documents https://popXXXXXX@cloud.uni-konstanz.de/remote.php/webdav/Documents "

You can also access the data in your cloud from a mobile client via an app password. Should your device be stolen or if your app password is hacked, the attacker would not gain access to your university account and would not be able to misuse university services such as your e-mail address. Should access via the app password be compromised, you can cancel access directly from the web interface and/or set a new app password.

You can set up an app password in your account settings under "Security“ https://cloud.uni-konstanz.de/index.php/settings/user/security.

In the web interface under "Help“: https://cloud.uni-konstanz.de/index.php/settings/help

The KIM offers SOGo for calendaring.
If the calendar in nextcloud was activated, we would be duplicating services, which we are actively trying to avoid. We have therefore also not activated the address book and webmail functionality, as these are available through SOGo which provides a much greater range of functions.
