DR setup

[Erk]

I am looking at setting up a Proxmox 2.0 server at a Disaster Recovery site several kilometres away from the main site. The link between the two sites will be modest, about 10Mbps, so that rules out a fast common storage setup.

Can a useful cluster still be created over this kind of link? If not what sort of replication would you suggest?

Hi,
perhaps with an asyncronous drbd-connection (with drbd-proxy - IMHO not free)?

Ask the drbd-people.

With only 10Mbps it is difficult to have any sort of useful real-time VM replication going on.

We have some sites that require a DR site and we use simple old school reliable technologies:
1. Web content/code is rsynced daily to the DR site
2. After the daily DB backup is created we rsync that DB backup to the DR site

In our case we are using MSSQL for the DB.
MSSQL creates the DB backup file, we then use gzip with the rsyncable option to compress the backup.
Over a 10Mbps connection it usually takes less than 15 minutes to complete the rsync of a DB that is about 3.5GB gzipped.
