Hi,
I'm using an external 4-disk bay connected via USB-C for backup and data storage purposes. Since I still have one disk-slot left I was wondering whether adding a parity-disk with SnapRAID for an additional layer of security is a good idea. But before I make that investment I've a few questions, that hopefully some of you could help me answer:
- Is it generally considered a good idea using something like SnapRAID on external drives?
- I've currently about 25 TB of data spread over three disks in that bay, how long would a regular SnapRAID sync roughly take (just a very rough estimation, are we talking days, hours, minutes)?
- Does the Sync-Time depend on how much data is changed? Most of the data will probably stay the same, so will this fasten sync times or will it still do a complete disk scan every time?
- How does SnapRAID deal with being disrupted? There will be cases in which the machine isn't running long enough for a complete sync. How does SnapRAID behave if I turn it off before it has completed. Does it support some kind of resume?
- Are there any other tools I should look at instead?
