The appliance supports iSCSI targets but prior to RAID array creation, you must decide how much space you want to keep aside for these. Target creation is simple and iSCSI thin provisioning is supported so you can create targets that only use a small amount of space on the appliance but appear much larger to the host. As more data is stored on the target, the appliance dynamically allocates extra space to it.
IP SAN support extends to thinly provisioned iSCSI targets for better storage usage.
For workstation backup Thecus includes a single-user copy of Acronis True Image Personal which does not support Windows Server. It takes manual backups of files and folders or entire drives as images to the appliance and can create a bootable disaster recovery disk. However, this is a heavily stripped down version so if you want job scheduling, disk cloning, incremental backups and more you must upgrade.
Other backup options include support for Rsync where the appliance acts as a target for other appliances. A free add-on module allows it to replicate to other targets and another enables scheduled backups to locally connected USB and eSATA devices. The appliance's operating system is also protected by Thecus' dual-DOMs. The second DOM automatically maintains a backup copy which is called upon if the primary one fails and you can schedule regular backups too.
Many vendors are adding cloud-based services to their appliances but Thecus isn't one of them. So far, the best example we've seen of this feature is QNap's MyCloudNAS service which allows you to use the appliance to provide your own secure cloud backup, multimedia and file sharing services to remote workers.
The N5200XXX delivered respectable results in our performance tests. Using a Broadberry dual Opteron 4162-equipped rack server running Windows Server 2008 R2 64-bit, drag and drop copies of a 2.52GB video clip returned read and write speeds of 89MB/s and 86MB/s. Our 17.4GB collection of 10,500 files was also handled well with this folder copied to the appliance at a rate of 60MB/s.
