What speed do you need to back up 256 GB in 8 hours? 71.11 Mbps
You need 71.11 Mbps at peak rate to copy 256 GB in eight hours. Gigabit Ethernet provides a large margin for a reliable overnight photo backup.
A 256 GB photo shoot needs 71.11 Mbps to copy within an eight-hour window at peak rate. That is a modest raw requirement, so almost any wired network and many modern wireless links can meet it. The harder part is making the overnight backup consistent when other traffic and drive behavior are included.

How this is calculated
The calculation uses 256 billion bytes, eight bits per byte, and 28,800 seconds. The result is 71.11 Mbps. A Gigabit Ethernet link is comfortably above that floor, while a busy WiFi connection can still miss it if the signal is weak or the link is shared. A wired backup also avoids the sleep, roaming, and interference events that make overnight jobs less predictable.
Verdict
The raw deadline is easy for Gigabit Ethernet, which could move the same 256 GB in about 34 minutes at peak. That gap is useful because photo backups often contain many files, trigger filesystem work, and compete with other traffic. The calculator gives the minimum equation result, while the recommended wired link gives the operational margin a nightly workflow usually needs.
