5 OSS File Synchronization
This section describes the features and options available for the synchronization of
OSS files and directories. These features apply to both one-time synchronization and
scheduled synchronization.
OSS File Sets
AutoSYNC supports synchronization of OSS file sets. Each synchronization file set can
be either a set of OSS files and directories or a set of Guardian files. An OSS file set is
described using an absolute pathname that can include the /E directory and the
Expand node name (/E/PARIS). The source and destination file set can specify either
an absolute directory name or an absolute file name. The following rules apply:
•
The complete directory tree with all its subdirectories is synchronized.
•
If the directory tree does not exist at the destination location, all the missing parts
of the directory are created.
•
If the source directory is empty or no files were selected for synchronization, an
empty directory is created.
The source and destination pathname specified in AutoSYNC commands each can be
at most 128 bytes long. Internally, when traversing directory trees, AutoSYNC supports
a pathname with a maximum length of 1024 bytes.
Some AutoSYNC commands such as INFO SYNCFILESET truncate displayed
pathnames if the pathname exceeds one line. In such cases, the trailing portion of the
pathname is displayed and the abbreviated name is preceded with ellipses (...) to
signify that the pathname was shortened. If the DETAIL or LOG options are specified
with these commands, the complete OSS pathname is displayed. Pathnames wrap to
the next line if necessary.
AutoSYNC synchronizes the following OSS disk files:
•
Directories
•
Regular files
•
Symbolic links
•
Hard links
Unlike an empty Guardian file system subvolume, an empty directory is synchronized.
