Title

Characterlimit in backup/restore path
Description

Is there a character limit for the length of a backup or restore path in Netvault?

Resolution

Backup file path length limitations:

The maximum length of a backup file path depends on the operating system and the file system the data resides on.

•

On Windows, the maximum length for a path is 260 characters. It includes a drive letter, colon, backslash, components separated by backslashes, and a terminating null character (for example, D:\<256 chars>NUL). Windows also supports extended-length path of up to of 32,767 characters. It includes components separated by backslashes, each up to 255 characters in length (for example, “\\?\D:\very long path”).

•

On Linux and UNIX platforms, the maximum length for a path is 1024 characters, including the target filename and path. The path can consist of a maximum of 255 elements. An element here refers to individual directory named in the path as well as the target filename. Restores of data to platforms or file systems with different namespace support may result in truncation of some path elements. These limitations do not apply to all UNIX file systems, particularly ZFS.

For backups of Linux and UNIX clients, NetVault Backup uses the cpio tape format that does not impose these limitations. However, OS imposed limitations do apply. For more information about the OS imposed limitations, see the relevant OS documentation.
