Copy time machine backups

New to the forum.

I have an older (june 2011) NV+ ReadyNas with 4 x 1TB drives system which I use between linux/Mac & windows systems (NFS/AFP & CIFS), plus I use it for 2 Mac systems for time machine.

Currently its running at 99% full and its deleting old Time Machine backups to make space.
I cannot really upgrade the drives (largest officially supported drive is 1.5tb) so I need to make a choice of either replacing the ReadyNas with a new ReadyNas 314 (as recommend on another post) with 4 x 3TB or 4x4TB drives , or buying another older system from "flea bay" and copy over the regular NAS data to this replacement.

If I go down the completely replacement system, how do I carry over the old Time Machine backups?

Would the "forum" replace or add a second ReadyNas?

    The NV+ you have will run 2 TB drives, the ceiling is not 1.5 TB. There are 11 2-TB drives on the NV+ (v1 not v2) HCL, The current HCL is here: http://kb.netgear.com/app/answers/detail/a_id/20641

    Unfortunately your two best disk choices (in my view anyway) are not on the HCL for the NV+. They are the WD20EFRX and the ST2000VN000. Since your NAS has at least another 9 months of warranty that puts you into a somewhat difficult spot.

    You have one additional option you might consider - getting an additional NAS instead of retiring the NV+. Then split your data between the two units. For sizing purposes, you really don't want your NAS to be more than about 75% full. Somewhere between 80 and 90% you start seeing significant performance issues as the file system heroically but unsuccessfully tries to avoid fragmentation.

    I'm not a Mac user, so hopefully someone else can tell you how to carry over the time machine backups. Though if you add a NAS you can potentially avoid that (using your NV+ only for time machine, and the second NAS for everything else).
  • Thanks Stephan,
    I did notice that the list was updated late last night to 2tb drives.

    I know running a nas or any storage over 75% is bad, however, when free space is reported at 60% its not really my fault as the Time Machine backups appear to be hidden in the free space area.

    If I do go down the second nas option then one will be pure Time Machine and the other will be pure NAS.
