Re: mirroring a server and/or hot standby

Hello John,

 

Since you mentioned a different OS and want to copy the entire instance it would seem that pg_dumpall is the way to go.

 

You would then import the dump into the new instance using psql.

 

See:

http://www.postgresql.org/docs/9.4/static/app-pg-dumpall.html

http://www.postgresql.org/docs/9.4/static/app-psql.html

 

Best regards,

Holger Friedrich

Subject: [GENERAL] mirroring a server and/or hot standby

 

Hello All,

 

I am looking for documentation pointers on how to move the contents of an existing/working single-instance server to a new instance. As in: I have a Postgres server running in a VM and I want to move it to a different OS in a different VM guest. 

 

Is there a way to gracefully do this? Is there a way to "sync" to a new server? Do I need to do this the hard way by manually copying all the data over to a new server with SQL?

 

It seems that setting up a hot standby server may be the way to go but chapter 25 in the user doc is scant on setup/install detail for this configuration. I am also interested in setting up an offsite hot standby server for failover.

 

Suggestions for tools and/or further reading welcome!

 

Thanks in advance,

 

John
