Cavalry Storage CAND3001T0 1TB Network Drive ReviewNemo - February 4, 2009

This section allows you to create backup schedules to backup folders from the CAND3001T0 to another identical NAS device. According to the documentation, the files are encrypted and compressed before the duplicate process in order to secure the data as well as reduce the time of data transfer. Interestingly, there is no provided means provided to restore files and folders from the backup, nor does there seem to be any indication of the encryption key or compression algorithm used. You can only choose one folder at a time to back up and are limited to five scheduled backup jobs. There is no capability of monitoring the backup jobs to ascertain whether or not they ran.
You can use the built-in backup capabilities to backup the CAND3001T0 to an identical NAS device according to the user manual. I attempted to back up to the D-Link DNS-323 over the network and expected to see some sort of error in the system logs, but there was nothing there so I am not certain the scheduled job ever started. Without having an identical device to test with, there was no sure way to test this functionality, or so I thought. After exchanging several e-mails with Cavalry's technical support folks I found out that an “identical NAS” could be the CAND3001T0 itself. So I set up another backup task setting the destination address as the IP of the review unit and chose a folder to back up. At the prescribed time the job kicked off and this time I did see an entry in the logs showing a mount request for the \backup directory. I left the job to run overnight as I managed to choose a directory with almost 1,000 files for a total of 33GB.
When I next checked the CAND3001T0 using My Computer in Windows, I was able to see a new directory called \backup off the root of the volume and could navigate to where all the backup files were located. So far so good, except that I could not access them through Windows as I got “Access is denied” errors. Even when I mapped a drive using the login credentials of the administrator account on the CAND3001T0 I could not open or copy any files. I decided to make one last attempt using my rudimentary Linux skills. I connected to the device through telnet, which gave me access to a Linux shell, and then I browsed to the backup file folder. I then tried to do a "restore" by copying the files out of the \backup directory to the \public folder hoping it would work in Linux, but no such luck as I still got “Permission denied” on all the files I tried to copy.
That just about wraps up the configuration options. All that's left is to take a look at the logging capabilities.
