Tivoli Storage Manager for UNIX Backup-Archive Clients Installation and User's Guide
The Copy Mode attribute determines whether a file or directory
is considered for incremental backup regardless of whether it changed or not
since the last backup. Tivoli Storage Manager does not check the mode
for selective backups. The value for this parameter can be one of the
following:
- Modified.
The file is considered for incremental backup only if it has
changed since the last backup. A file is considered changed if any of
the following are true:
- The date or time of the last modification is different.
- The file size is different.
- The file attributes, with the exception of archive, are different.
However, if only the file meta-data changes (such as access permissions), but
the file data does not change, Tivoli Storage Manager may back up only the
meta-data.
- The file owner is different.
- The file permissions are different.
- Absolute.
The file is considered for incremental backup regardless of whether it changed
since the last backup. For archive copy groups, the mode is always
absolute,
indicating that a file is archived regardless of whether it changed since the
last archive request.
