#70 Request: Preserve Timeline history files

[Josh Berkus]

Feature Request: Barman should preserve history files in the WAL archive indefinitely.

The way it is in 1.4.0:

Timeline history files, i.e. 0000000002.history, are subject to the same expiration rules as regular WAL files. This creates a problem if you try to use a Barman restore to restore to two different servers and set up a master-replica relationship, per this issue on Hackers:

http://www.postgresql.org/message-id/5579E7DE.6020109@agliodbs.com

This means that, once the history file has been expired and deleted, there is no way you can use Barman backup to restore both a master and a replica.

The way it should be:

While we hope that PostgreSQL will fix this bug, the fix may not be backported. As such, it would be useful if Barman preserved the history files:

1. .history files should not be subject to deletion when backup snapshots expire;

2. all .history files should be restored with the restored WAL.

Of course, if this is somehow already fixed in 2.0, please let me know and we'll upgrade. Thanks!
