Which RAID when backing up from local to remote readynas?
Hello readyNAS wizards! I'm just about to buy 2 ReadyNAS Ultra 2 with either 1X2TB or 2X2TB in each. I have a couple of brainteaser (perhaps) questions: One will be at my place, the other at my...
First, allow to express that if you intend to utilize just 1 share on both sides of this rsync connection, there are too many variables and possible problems that could arise. What I would recommend and is possible usring Rsync is to have 2 sets of shares, 1 to back from local to remote NAS, the other to backup from remote to local NAS. Again I am indicating 2 shares per NAS, a total of 4 shares.
Second, RAID0 can be used, the general bad idea here is that if one of the disks fails or drops out of the array, you will lose all the data on the unit. As long as all of the data is backed up on a differnt unit or hard-drive and you aren't concerned about copying your data back onto the unit after replacing or resyncing a drive each time, then perhaps it will be useful to you.
Finally, there is no file system you can us with only 2 drives that will allow you the performance you are seeking short of RAID 0, which we have just discussed.
