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 parents place. I will be backing up the two devices to each other using Rsync, perhaps not all the files, but at least the back-up shares. To explain: Back-ups of my Macs (Time Machine) and PC on my local readyNAS in backup share 1 need to be synced to the remote readynas on backup share 2, and the back-ups of alle my parents photos, videos and Time Mahine backups on the remote backup share 1 needs to be synced to backup share 2 on my local ReadyNAS. This to protect against fire, theft etc. Will i be able to do this with Rsync?
Another question - using X-RAID for disk redundancy will leave me only half the disk space I could have on the readyNAS, if I choose RAID0 (I think that's the one that gives you 4 TB from 2X2TB). Using X-RAID gives you a local backup, but since I will be backing up all the important files to the remote readyNAS anyway, won't it be overkill to also have a local mirroring of the backup from my computers? Or am I missing something?
If I choose to only buy 1X2TB for each NAS - Is there a RAID file system that will allow me to purchase a second harddrive in the future to expand the capacity without just making the new disk a redundant mirror? I mean a file system that makes it easy, like just inserting the extra drive without having to do too much programming.
Thank you for any answers you can give. I need to make a system that works continuously automatically in the background, to minimize the support I have to give parents, girlfriend etc.
Sincerely
Stian

- 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. - Thank you for a clear and direct answer! I just ordered each NAS with 2x2TB, and will use the X-RAID file system. I was trying to explain the same thing you recommend here - have 2 sets of share pr NAS - ie backup share 1 and 2 on each of the NAS'es. In addition I will have a Media share on each one, for other files that aren't as invaluable.
- If you are going to operating from the files on the NAS, you may want to use a more descriptive name such as oper rather than backup1. Use the default backup for the remote NAS, then back up your operational files (oper) to the backup share on the remote NAS. That would give you three shares, the default backup and media and oper (or operational if you prefer, I have an old habit of short folder names).
Just be sure to not put your photos in the default photo folder under the default share media. It would not be backed up under your design. I would create a photo folder that is under a share that is backed up. (my photos are under the media share, but it is rsynched to the media share on the second NAS).
