| + | ==Q: We want to back up our MRI data and are expecting to collect multiple terabytes of imaging data over the next few years. Do you have a specific suggestion for us? I was looking at the DS416 option from the wiki and also saw a 2-bay system== | ||
| + | |||
| + | A: The key is to have a RAID system 1 or higher, so you have redundancy if one of the drives fails. See here: https:// | ||

| + | |||
| + | ==Q: Is it possible to purchase just 1 internal hard drive for now - or would you not recommend this - and if so do you have any good brands or suggestions? | ||
| + | |||
| + | No, you want two drives at a minimum so you can at least do RAID 1. You can start with two drives, and then add more and expand the raid volume later. (At least with the Synology systems) you can start with RAID 1 and then switch to RAID 5 or 6. Also, each drive is limited to use the size of the smallest drive in the raid, so if you start with 2TB drives, you'll want to expand in the future with 2TB drives (or larger drives, but only 2TB of each one will get used). | ||

| This is a service that provides very easy access to a modern robot-controlled high-availability tape archiving system. It provides a simple filesystem-view interface with simple file retrieval. Custom linux commands are provided for the user to make their archiving copies. Note that this is an **archiving** service, and is not meant to be a regular backup service. You are able to retrieve files, but such retrievals are expected to be rare. | This is a service that provides very easy access to a modern robot-controlled high-availability tape archiving system.
