If users have shared files open, data might be lost. Be sure to have all users save their changes and close any open files before you shut down the storage system.
64 4 File Sharing and System Backup 4.1 File Sharing The freeS tor 4020 allows users to share files quickly and easily , using multiple operating systems. By default, there is one shared folder called “public” that is accessible by all users. Additional shared folders can be created by using the W eb Management Interface.
65 3. In the Drive list, select the drive letter that you want to assign to the shared folder . 4. In the Folder text box, enter the following: “storage_systemshared_folder” where storage_system is the name or IP address of the storage system, and shared_folder is the name of the shared folder .

78 4.2.6 Protecting Your Disks After you inst all DiskSafe Express and restart your computer , the Protect a Disk wizard runs automatically . Using this wizard, you can specify which disk or partition.
79 In addition, you can recover a data disk or p artition using DiskSafe Express, but you can recover a system disk or partition only using the recovery CD, so if you have separate partitions for your system information and y our dat a, you might want to protect each one separately .
80 From the Discovered storage systems list, select the stora ge system where you want to back up the selected disk. The na me of the storage system automatically appears in the S torage system name or IP address text box.
81 (Figure 4-14). Figure 4-14: Previously Backed Up Pa ge If you select Re-use the existing backup, you must select which backup t o reuse from the list. Then click “Next” and go to the n ext step. If you select Create a new backup and click “Next”, you must select the desired backup location as described in step 4.

83 system, you will not be prompted to prov ide this p assword again. However , if you protect a second disk using a dif ferent storage system, you will be prompted to provide a password for that storage system. • Y ou can change this password later using DiskSafe Express.
84 If you want to protect additional disks or partition s, repeat this procedure for each one. Note: If you subsequently change the drive letter of a protected disk or p artition, you must restart DiskSafe Express to update this application.
85 4. If you’re stopping a backup, the backup stops immediately . 5. If you’re stopping a recovery , a confirmation message appears. Click “OK” to stop the recovery now , or click “Cancel” to proceed with it. 4.2.9 Changing the Backup Schedule When you protect a disk, you specify when you want backups to oc cur .

91 In most cases, there will be only one NIC, and you can simply select “Next”. This screen displays only the NICs on this system that are supported by DiskSafe Express. If no NICs appear on this screen, you might need to install a n appropriate network driver .
92 If you don’t remember your password, you can change it using the web interface and enter the new password here. 10. In the left column, select the backup that corresponds to the disk or p artition that you want to recover . If you protected only one disk or partition, only one item will appear in this list.
93 15. Select the disk where you want to recover the data, and select “Next”. Note: If you are recovering a system disk, the system to which you are recovering the data must be identical to the original system.
94 • T o restart the computer , select “Finish”. 20. When the computer restart s, use the appropriate procedure for your system to configure the computer to boot from the local hard disk once more. 21. S tart DiskSafe Express and remove protection from the recovered disk or partition (as described in the next section).
95 Appendix A: Disk Configurations Y our storage system supports the following types of disk configurations: • Linear: A linear configuration is similar to using multiple hard disks in a regular computer . Each disk is an independent entity , and the dat a on it is self-cont ained.
96 Y ou can use RAID 5 only if your storage system has at least three disks. If the disks are not the same size, the smallest of the disks determines how much disk sp ace is available for data. For example, if one disk is 300 GB, one is 400 GB, and one is 500 GB, only 300 GB from each disk can be used.
97 access all the dat a. In a normal state, you cannot add a disk to a RAID 0 or RAID 1 configuration. Any disk that you install will not be used u nless you subsequently reconfigure the storage system. W arning: Reconfiguring your storage system disks deletes all the dat a on your storage system.

After the storage system shut s down, re-install the same disk and then restart the system.
104 storage system is running, you can swap only two disks, and you must restart the system af ter you swap the disks. If you swap the disks when the storage system is not running, you can swap all four disks, and the system will function as it previously did when you restart it.
105 Note: If the firmware on your new unit is newer than the firmware on your hard disks, you might want to cont act your vendor about obt aining the latest firmware. Refer to “Upgrading the firmware” on page 62 for information about upgrading to newer firmware.
106 Appendix B: T roubleshooting Vie wing the system log The System Log page (Figure B-6) displays a list of event s that have occurred on the storage system. Reviewing this list can help you ident ify and resolve any problems that you might encounter .
107 B.1 Disconnecting from Shared Folders If you need to reconfigure the disks in your stora ge system or shut it down for any reason, all users should disconnect from the shared folders to ensure that the process proceeds smoothly .
108 The procedure for disconnecting from a shared folder on a Mac varies, depending on whether the Mac is running OS X or an older operating system. T o disconnect from a shared folder on a Mac running OS X: 1. On the desktop, select the shared folder from which you want to disconnect.
109 In addition, pressing this button restart s the storage system, which mightadversely af fect user connections to shared folders. Be sure to do this only whenusers are not connected to shared folders or performing recovery . Problem: The users can’t acce ss the shared folders.
110 IP address and ending IP address must be the same. If the network configuration is correct and it still doesn’t work, the DHCP service might not be working properly . Restart the storage system. Problem: The users cannot access the storage system using FTP .
111 Note: When authentication errors occur , invalid backups might be created on the storage system. T o ensure that y ou don’t use up disk sp ace unnecessarily , be sure to delete any extraneous backup s on th e storage sy stem.
112 • If the IP address of the storage system changed (for example, if the storage system obtains it s IP address fr om a DHCP server and acquired a new one af ter you added the storage system to the list of backup locations), you must st art DiskSafe Express so that it can retrieve the new IP a ddress.
113 Once the file has been created, you can send it to T echnical Support. Using the recovery CD T o create a diagnostic file using the recovery CD: 1. Insert the recovery CD into the computer ’s CD-ROM drive and press Alt+F2. 2. At the command line, enter the following command and then press Enter: “xray” 3.
