1 TB is a large data size, and it will take 3 to 24 hours, depending on the backing-up speed every second.

Assume that the backing-up speed is 10MB/s; it will take about a whole day to complete the full backup process. If the transferring speed is 100MB/s, the backup process only takes about 3 hours. The transferring speed is affected by various factors, like the backup tool you use, hardware condition, drive interface, etc., and bad sectors will also influence the transferring speed.

To ensure a smooth and quick backup process, you can use professional backup software, like EaseUS Todo Backup. It can help you effectively manage your data backups with a few clicks, including full backup, incremental backup, differential backup, compressed backup etc. It provides a relatively fast backup speed that more than 100MB/S to help back up your 1TB data quickly, and it won't lose any data during the backup process. It allows you to store your backups to multiple devices, including internal & external hard drives, Cloud services, NAS, and security zone.

Before starting, you need to make sure the backup storage space is larger than 1 TB and use a USB 3.0 and SATA cable to connect your target disk. The backup process should not take too long if all these are prepared well.

In conclusion, how long it takes to back up 1 TB of data depends on the backup speed every second and various factors influencing the process. Still, with a professional and reliable backup tool like EaseUS Todo Backup, you can perform the task in just several hours.
