Two Syno's back each other?

Postby NasNewb » Thu Feb 02, 2012 4:09 am

So, my DS212 (Syno1) is on order, with 2 x 2TB drives (A & B). My brother (across the 'net) will have the same setup (Syno2). My scenario:

Syno1 stores my data on drive A
Syno1 backs his data on drive B
Syno2 stores his data on drive A
Syno2 backs my data on drive B

Is this feasible? I would like to direct where my files backup to (drive B) after I choose the server (Syno2). But, I am failing to see such option.

Am I missing something or going about this all wrong?

Thanks.

You mean you want to backup

1) syno1/driveA to syno2/driveB
and
2) syno2/driveA to syno1/driveB?

Yes this is possible. While setting up a backup task, you can choose the destination device AND share.

Exactly.

It brings comfort to receive a positive answer and I look forward to setting it up. Though, I must admit that I have been troubled to not be able to find such level of detailed instruction, such as:
http://forum.synology.com/wiki/index.ph ... in_DSM_2.2

Is there some other source that shows otherwise, in more detail? Otherwise, I suppose I'll be back here seeking step by step directions!

Thanks.

The Wiki doesnt seem to be up to date. On earlier FW you could not choose the destination folder, now this has been added as an additional step of the netbackup wizzard.

Can I make a suggestion?

Why would you dedicate your data and your brother's data to separate hard disks, apart from perhaps preserving all your available disk space of both hard disks? That is the only reason I can think of, but I am feeling some concern about data loss in your request.

You could also create a RAID1 set with the advantage of protecting your data against a hard disk failure without having to restore. The RAID1 set would rebuild itself when you replace the failed hard disk. while dat will remain available... And the restore option is still available, also offering a way to recover certain file that have been deleted and need to be recovered (even if you already would have cleaned the recycle bin, or if you would not have activated it).

Since you can choose the folder to backup to, your data and your brother's data would not get mixed up. Even if you would like to separate it on different volumes in one DiskStation, DSM 3.2 already allows to create multiple volumes on one storage type. So, you could create a RAID1 set with 2 volumes (one for data, one for your brother's backup data and the other way around on the other box). This way your cross-backup requirement over the internet has been met, and you have the avantage of RAID1. Your data as well as your brother's data will exist 4 times: live data on RAID1 (2) + backup data on RAID1 (2)!!!

Just an idea...

I'm considering to setup a similar solution with a friend.

Question 1:
If doing like "Fit" is suggestion, i.e. having 2 volumes on RAID1 on both of the NAS (one with own data, and the other with a friends backup), is it then possible to encrypt my data on the volume on my friends NAS so that he can't read my data, and the other way around for his data on my NAS ??

Question 2:
Another way to set this up would be to each attach a USB disk to our NAS, and then I backup my data on the USB disk attached to his NAS, and vice versa. Is that at all possible, or is that not supported ??

Br,
Jonas

Wouldn't this reduce the available space by 50% compared to the original proposal?
