Super Slow Upload

Thread needs solution

I just bought Acroins Home, with a 3TB online disk. Upload or 1.9TB is super slow, after hours 24GB are uploaded. Calculating time remaining... is displayed all the time. MAC. OS 12.3.1, M1.

The upload speed for ATI/ATCPHO is quite slow, and can vary across the Acronis servers and from day to day, even hour to hour. In part this can be due to load balancing, in part it is due to the way in which the backup is created, which requires encryption (if selected - and you really should) and advanced features such as deduplication, which require extensive processing on the PC/MAC. The best peak upload speed I have seen was about 26Mbps, and I have seen it as low as 6Mbps. The speed of you internet connection does not have any appreciable impact once the upload speed exceeds 30 Mbps. I found this to be so with my old 100/40 Mbps cable connection.

I have found it best to do a series of smaller backups rather than one large backup; I can then vary the frequency of individual backup tasks to reflect the importance of the data and the rate of change in that data.
