*The display is a tax separate price.
We adopt Oracle Solaris 11 ZFS as the file system
TeraCLOUD creates a ZFS file system * for each customer's account, and the capacity is set as the quota (capacity limit) value of ZFS.
We store ZFS snapshots for each of our ZFS file systems. The snapshot saves the state of the file at that moment, does not require additional capacity at the time of creation, and consumes capacity due to subsequent data changes.
Since TeraCLOUD holds up to 8 generations at once every 3 hours and once for each day up to 14 generations, you can download data that you accidentally deleted or overwritten from the snapshot.
*Data not stored in the ZFS snapshot can not be downloaded.
This ZFS snapshot is saved using the free space of your data area, and it will be deleted automatically when the free space becomes small. Even if the ZFS snapshot is deleted, it will not affect current customer's data.
*Capacity of uploaded files and directories (folders) is calculated based on the value on ZFS. Therefore, since the calculation method differs from the file system (NTFS, FAT, exFAT, HFS +, ext etc) used by the customer's device, the capacity actually available differs greatly (about 70 to 130%) in usage I will.
