Qtrees enable you to partition your volumes into smaller segments that you can manage individually. You can set a qtree's size or security style, back it up, and restore it.
When to use qtrees Qtrees enable you to partition your data without incurring the overhead associated with a volume. You might create qtrees to organize your data, or to manage one or more of the following factors: quotas, backup strategy, security style, and CIFS oplocks setting.
How qtrees compare with FlexVol volumes
In general, qtrees are similar to FlexVol volumes. However, the two technologies have some key differences. Understanding these differences helps you choose between them when you design your storage architecture.
Qtree name restrictions
Qtree names can be no more than 64 characters in length. In addition, using some special characters in qtree names, such as commas and spaces, can cause problems with other Data ONTAP capabilities, and should be avoided.
