Compatibility of dump.rdb across versions

[Geoffrey Hoffman]

I'm running Redis 2.6.6 on my laptop; our dev server is running 2.6.8 and the latest download as I write this is 2.6.12.

Is dump.rdb compatible across these (minor) versions? Forward and backward?

Just wanted to check before I try to find older source downloads.

Cheers-

Geoff

Later Redis revisions should be able to read earlier dumps.

I can't remember if there were any breaking changes that would make 2.6.8 dumps not work in 2.6.6, but you should probably check the release notes and/or test before relying on the behavior.

I maintain a history of dump.rdb versions over here - 

https://github.com/sripathikrishnan/redis-rdb-tools/blob/master/docs/RDB_Version_History.textile

The current version of the dump file is 6. This was introduced before 2.6 was officially released. After that, there hasn't been any change to the dump file format. 

In short, a 2.6.8 and 2.6.6 dump are identical.

Well, the fun never ends, does it? I've just discovered that my client's IT team has a pretty strict policy of using the approved Debian dpkg versions (Redis 1.2.4?!) but they're willing to use 2.4.14 from wheezy, but not 2.6.7 from Sid. Naturally, I built their app on Redis 2.6, which leads to my follow up question:

Is there any way to take a dump.rdb from 2.6.x and back-port it to 2.4.x ? What about an AOF? I have only about 20mb of data, and nothing in my code requires any feature added since 2.6.0, only that I happen to be using 2.6 on my development server.

Sure, there is. Read https://github.com/sripathikrishnan/redis-rdb-tools/blob/master/docs/RDB_Version_History.textile

Go back all the way to version 3 of the dump file and you should be good.
