Backups are usually considered data which is taken of a system and held somewhere else to be restored later. (EG a tape backup, a rdiff backup, etc). Netapp snapshots are not backups in that sense. What you get is the ability to go into a .snapshot directory and look at what was present at a certain point to certain limits (netapp snapshots are similar (but not the same) to a hardlink list of data on disk at a certain time. You can only change so much or keep so many before you run out of snapshot space and those go away). Snapshots can be seen on certain machines by going into the .snapshot directory. >> >> There's also a snapmirror from phx2 to offsite space in rdu2. > > What exactly does this mean? The Red Hat Netapps regularly copy the data from RDU2 to PHX2. As long as we don't change too much over on PHX2, then the RDU2 side is within sync with PHX2 within an hour. If we have a large delta or other network traffic is full it can take many hours or certain snapshots may get 'dropped' because they are no longer possible to reconstruct. -- Stephen J Smoogen. _______________________________________________ infrastructure mailing list -- infrastructure@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to infrastructure-leave@xxxxxxxxxxxxxxxxxxxxxxx
