Most NAS devices released within the past year have at least 2 GB of RAM, so we stuck with that as our minimum. CPU and RAM: We preferred a reasonably powerful dual-core Intel Celeron processor, but we didn’t rule out ARM-based configurations as long as their processing speeds were similar.If you opt for a cheaper model, you usually sacrifice read and write speeds or end up with a less-polished operating system. More than that, and you’re entering more complex and powerful business-class territory. Price: For home use, you don’t need to pay more than around $250 to $350 for a two-bay NAS (not including the price of the hard drives, unfortunately).Single-drive NAS devices don’t provide this sort of data protection, and NAS boxes with more bays introduce more complex RAID configurations, such as RAID 5, RAID 6, or RAID 10, that require more planning and research to configure. As a result, your data remains safe and accessible even if a drive fails. This setup gives you half the NAS’s actual amount of storage for files: For example, a NAS with two 8 TB drives in RAID 1 still has 8 TB of total space available ( equivalent to about 300 Blu-rays), not 16 TB. For most home uses, a two-drive NAS is just right because it protects your data by mirroring the contents of one drive to the other (a configuration known as RAID 1, or a mirrored array). Two drive bays: Hundreds of NAS devices are available, and you can find models with one, two, four, eight, or more drive bays.This might be something to think about as well. Leroydouglas also wrote a nice article about Boot Clones. That leaves open the possibility of a deadlock where they cannot complete due to lack of space, discovered late in the process. Note that every other backup method pays this same "computing what needs to be backed up" time penalty, but some hide it by overlapping it with copying files. Otherwise, it may take several hours of computation just to decide what needs to be backed up, before any files are transferred. If you choose to connect your Time Machine backup drive only from time-to-time, try to do so at least every-other day, at minimum. When you need it, your Time Machine Backup is much more likely to be there.īack up your Mac with Time Machine - Apple Support You do not have to set aside a "Special Time" when you only do backups. Time machine's "claim to fame" is that it is the backup that gets done, because it does not ruin performance of the rest of the computer while doing its backup operations. So I am wondering if there is another backup solution (other than Time Machine or Synology's Cloud Station) that could maintain a "clone" of the RAW file partition, which could start automagically when the CalDigit is plugged in, and wouldn't start from scratch each time. My reticence with using Time Machine is how accessible the RAW files etc will be: For example - if the CalDigit blew up, how would I go about getting the data onto a brand new external drive from the Time Machine backup - so far I have only ever really had to use TM to restore to a new Mac when the old one is too old, and I wouldn't want to have to refresh the MacBook as part of the exercise. So I am wondering whether using Time Machine is a better solution to backup both the Mac and the CalDigit, using the NAS as the Time Machine Drive. It is this software that "forgets" the drive it is backing up, making it essentially useless for my purposes! The current backup of the RAW files partition is not handled by Time Machine, but by the Synology Cloud Station Backup software running on the MacBook. What is the best solution I should use (happy to buy backup software if needed)? Should I just scrap the TM partition on the CalDigit and set TM to backup the CalDigit and the HDD to the NAS?īut as these are RAW files etc, I'm not sure I really need the versioning that TM gives me: A fair percentage of the RAW files may be scrapped straight after import to Lightroom. It also seems to start from scratch again taking a considerable time. This worked fine (albeit slightly slowly) for the first pass, but then each time the external drive is disconnected, you have to reselect it in the cloud station software before it will resume backing up. I recently purchased a Synology NAS and thought I could backup the RAW file partition with the Synology Cloud Station Backup software, while leaving the Mac backing up via Time Machine to the CalDigit. The CalDigit has two partitions - 1 for Time Machine Backups of the MacBook pro and a larger partition for storage of RAW camera files, video files and sound files. We have a MacBook pro with an external CalDigit raid drive (RAID 5) connected via Thunderbolt 2.
