- Backups made to tape and sent off-site at regular intervals.
- Backups made to disk on-site and automatically copied to off-site disk, or made directly to off-site disk.
- Replication of data to an off-site location, which overcomes the need to restore the data (only the systems then need to be restored or synced). This generally makes use of storage area network (SAN) technology.
- High availability systems which keep both the data and system replicated off-site, enabling continuous access to systems and data.
