In the field next to "Folder:" enter \\daten.uni-oldenburg.de\myhome and then click on "Finish" (see following figure). Ticking the box to restore the connection when logging in requires that your system knows the access data.

Step 4: If your system does not already know the access data, you should see the following dialogue window to request this data. As shown in the following illustration, you must enter w2kroot\ followed by your abbreviation (e.g. abcd1234) as the user name. Then press "Ok" to confirm.

Step 5: You should then be able to find the home drive as Connected in the file explorer (see following figure).

Step 1: Switch to the "Finder menu" (recognisable by the word "Finder" next to the Apple symbol) and open the menu item "Go to". Then click on "Connect to server..." (see following illustration).

Step 2: In the dialogue window that now opens (see following figure), enter smb://daten.uni-oldenburg.de/myhome and then click on "Connect".

Step 3: If your system does not already know the access data, you should see the following dialogue window to request this data. As shown in the following illustration, you must use your abbreviation (e.g. abcd1234) as the name. Then click on "Connect" to confirm.

Step 4: You should then be able to see the home drive as Connected in the Finder (see the following illustration of an open home drive). You can now also find the home drive within volumes.

Step 2: Now enter smb://daten.uni-oldenburg.de/myhome in the lower area (see lower red marker in the following figure) and then click on "Connect"

Step 3: If the access data for the home drive is not yet known to your system, a dialogue window for entering this data is displayed (see following illustration). Enter your abbreviation (e.g. abcd1234) as the user name and w2kroot as the domain. Then confirm with "Connect".

Step 4: You should then be able to find the home drive as Connected in the file explorer under "Network" or in the favourites list (see markings in the following illustration).

Step 5: To add the home drive or a folder contained in it to the favourites of your file explorer, open it and click on the button with the three dots next to the currently open path (see following figure). 
In the menu that now opens, you can add the currently open path to your favourites by clicking on "Add to bookmarks".

Step 1: Open the home drive and the corresponding folder in the file explorer where you have noticed a file loss. Then click on the menu item with three dots, as shown in the following illustration. In the selection that then opens, you must select "Properties".

Step 2: In the window that now opens, click on the "Previous versions" tab.

Step 3: In the "Previous versions" tab, you can select from the existing backups of the folder. After making the appropriate selection, you have the option of opening a previous version of the folder by clicking on "Open" (marker no. 1 in the following illustration) or restoring the entire folder to the selected point in time by clicking on "Restore" (marker no. 2).

Step 4: If you clicked on "Open" in step 3, you should see the selected backup open in the file explorer (see following illustration). You can now copy the objects you want to restore to the original directory from the home drive.

Step 5: If you clicked on "Restore" in step 3, you will be asked to confirm the action for security reasons (see following illustration). If you are sure, click on Restore.
