Nearline storage is a hybrid disk/tape filesystem with a layout like [[Project layout|Project]]. except that it can virtualize files by moving them to tape-based storage on criteria such as age and size, and then back again upon read or recall operations. This is a way to manage less-used files. On tape, the files do not consume any of your quotas other than nearline and they can still be accessed, albeit more slowly than with the home, scratch and project filesystems. | Nearline storage is a hybrid disk/tape filesystem with a layout like [[Project layout|Project]], which however uses its hybrid nature to take advantage of both the the large amount of inexpensive storage available by tape and the rapid access to data that disk offers. | ||
