Fwd: Does observium support snapshot.
Hey All,
Firstly, a big kudos to observium and for making the life of a n/w engineer tad better. :)
Now to my query,
I have a Subscription Edition installed. Was wondering if there is a way to setup two instances say master/slave where the master polls the data and sends a periodic snapshot to the slave. This is basically for backups.
Any pointers in this regard would be much appreciated.
Feel free to revert if any questions.
Thanks

Hi Varun,
I believe what you are looking for is rsync and mysqldump? :-)
We don't do any sort of master/slave set up but for backup purposes you just need to copy the rrd directory and mysql database to another host.
Make sure the version of Observium installed on there is identical though, or it won't understand the other guy's database structure. (or just rsync the entire /opt/observium directory).

But won't there be any issues with the RRD files being read by rsync at some arbitrary moment when they are in an inconsistent state? The poller constantly updates them. Just thinking... :)

Hi Attila,
You can try using LVM snapshots to fix that ;-) But I've not had this issue before. RRDtool "mmaps" the file into memory, so I think it's pretty much updated instantly.
Unfortunately I don't have any other suggestions to make...

We use rsync & mysqldump for our daily backups. A restore to a DR environment is as simple as building a fresh install, svn to correct level (svn rev stored in tarball name) and untar the archive.
We actually run the rrd & mibs dirs from a ramdisk to reduce the chatter on our nas. We rsync that back to disk every 20-30 mins. Seems to work reliably for us, never had any noticeable rrd corruption.
