Re: [BackupPC-users] Multiple CPU usage for compression?

[Craig B. <cba...@us...>]

Each rsync backup has two processes on the backup server, but only one will
be doing compression.  So, yes, compression for a single backup is
single-threaded (as rsync is).

However, the backup server usually runs multiple backups (configurable),
and, in the steady state, the amount of compression required isn't very
large: only new files not already in the pool need to be compressed.  It's
not likely compression is a bottleneck.
