5.2.3 WebDAV issues

Storing files on a Web-based Distributed Authoring and Versioning (WebDAV)

server has become more popular in the last few years for sharing files (pictures,

music and video files, etc.). Many Internet Service Providers (ISPs) offer their

customers disk space on a WebDAV server as part of their contract.

In this section, we show you some common problems when you use a WebDAV

server on the Internet as a remote backup location for your files using Tivoli

Continuous Data Protection for Files.

Chapter 5. Troubleshooting, hints, and tips 305

Using a WebDAV server as a remote backup location

From the Back up to: list on the Remote Storage page of the Settings Notebook

you need to select Web Server (WebDAV) if you want to use a WebDAV server

as the remote location for storing your files.

You need to use the correct syntax as given by your ISP or administrator in the

Location: field when specifying the URL address of your WebDAV server.

If the IP address of your WebDAV server is for example webdav.server.net, you

need to specify the following URL in the Location: field on the Remote Storage

page:

https://webdav.server.net

Figure 5-49 on page 306 displays an example using a WebDAV server with

webdav.server.net as the IP address. In this example we defined to keep five

versions of a file on the WebDAV server using 5 GB as the maximum space.

Wrong user name and/or password

In addition to using the correct URL for your WebDAV server, you need to know

and specify a valid user name and password for Tivoli Continuous Data

Protection for Files to be able to communicate with the WebDAV server.

Tivoli Continuous Data Protection for Files displays an informational message in

the notification area that a password is needed for backing up files to the remote

location (see Figure 5-50 on page 307).

Chapter 5. Troubleshooting, hints, and tips 307

Figure 5-50 Tivoli Continuous Data Protection for Files needs a password (informational

message)

A new Web browser window opens prompting you to enter a user name and

password to access the WebDAV server (see Figure 5-51).

Figure 5-51 Tivoli Continuous Data Protection for Files prompts for a password to access

the WebDAV server

You need to enter the user name and password as given to you by your ISP or

administrator (see Figure 5-52 on page 308).

Figure 5-52 Entering user name and password

The password needs to be entered twice to confirm its validity. If both passwords

do not match, Tivoli Continuous Data Protection for Files opens a window

informing you about this situation (see Figure 5-53).

Figure 5-53 The two passwords do not match

If both passwords are identical but wrong, or if the user name is not correct, Tivoli

Continuous Data Protection for Files cannot successfully connect to the WebDAV

server. If this happens, Tivoli Continuous Data Protection for Files keeps

prompting you for the (correct) user name and password until you enter a correct

user name and password (see Figure 5-51 on page 307).

If you enter a correct user name and password, Tivoli Continuous Data

Protection for Files creates a password file in the \pwd\ folder of the data

directory with a similar name to the IP name of the WebDAV server (in our case

the file name is webdavservernet.pwd). This file contains encrypted information

to authenticate Tivoli Continuous Data Protection for Files with the WebDAV

server.
