Overview #
Cutback is a backup system with the goal of creating smaller, more focused backups by generating filtered file lists before archiving and keeping records of easily reaquirable files.
The backup strategy is broken up into discrete steps, each handled by a user-defined external application, and producing one or more files.
Before the backup is started, an identifier is generated from the date and the current backup index, which is incremented by 1 on each build for that date.
All files generated will have this identifier as it's file basename.
Search #
This step searches for files according to the following rules:
- Directories listed in the
pathsconfiguration variable are searched recursively. - Files matching patterns listed in the
excludesconfiguration variable are excluded entirely. - Files matching patterns listed in the
recordsconfiguration variable are added to a list of files to keep a record of.
Records are usually files that are low priority and easily reaquirable, such as movies, music, tv shows, etc.
This vastly improves the duration of the backup process, as well as the size of the resulting archive.
This list of records is located in the output directory, denoted with a
.records suffix.
All other files found within the search, are added to a list in the output directory,
called the manifest, and denoted with a .manifest suffix.
