How much data can I migrate with Data Transport?
You can migrate any amount of data. You can choose a Data Transport device model based on the amount of data that you need to migrate. The following models are available: Data Transport Micro (20 TB), Data Transport II (100 TB), and Data Transport III (1 PB). You can also use multiple Data Transport devices to migrate larger amounts of data.
How long does data migration take with a Data Transport device?
The Data Transport device uses two 10 Gbps network interfaces for data migration. The actual transfer speed depends on the read throughput of the data source, the bandwidth of the switch, and the number and size of the files. For example, the transfer speed is slower if you have many small files.
What data sources are supported?
Source: Files stored on local storage or Network Attached Storage (NAS).
Destination: Alibaba Cloud OSS.
Is data encrypted during migration?
Yes, it is.
How do I restart or shut down a Data Transport device?
You can shut down a Data Transport Micro device from the console.
For Data Transport II and III devices, run the reboot command in a terminal window to restart the device, or run the poweroff command to shut down the device.
