Can I use Rsync to synchronize my drive images offsite?
Following from the discussions above, We recommend that you select the underlying file system for Rsync, not a backup of the file system. However, having said that, drive images can be more suitable for Rsync than other types of backup, provided they are uncompressed and unencrypted. However, the checksum process will be CPU intensive. We have found on typical servers that checksums can be performed at a rate of about 100-120GB per hour, during which time the server’s CPU is at about 30% on a single core. [Note: on multi-core processors, this means that CPU usage is not particularly high.] So the time to backup via Rsync can be approximately calculated as: 2 * checksum time (one checksum for each end) + network time So the short answer is: if you really really want to do it, you can, but we believe there are better ways to achieve what you want to achieve. Remember – that the purpose of doing multiple backups is redundancy. That means protecting your data in different ways, to differen
