[BackupPC-users] rsyncd full backup

Hi Adam, The low I/O is when the machine is under load. Thank you for suggesting to use SSD. I have been thinking about that as well, but currently, the storage of BackupPC is using a 1TB disk, with about 80% utilization. Changing to 1TB SSD might be a little bit overkill on the customer's budge

Hi Timothy, I got the number by observing the output of iotop while file transfer is running. Also, on BackupPC host summary page, average transfer rate for full backup is also around 3MB/s It could be a network bottleneck also, as the customer is using 100Mbps switch with around 80 PC, not inclu
