-BackupPC you probably have existing uncompressed backups. You have
-several choices if you want to turn on compression. You can run
-the script BackupPC_compressPool to convert everything to compressed
-form. Or you can simply turn on compression, so that new backups
-will be compressed. This will increase the pool storage requirement,
-since both uncompressed and compressed copies of files will be stored.
-But eventually the old uncompressed backups will expire, recovering
-the pool storage. Please see the documentation for more details.
