Cache Directory Tagging Specification
TL;DR
Cache directories are essential for application performance but often lack standardization in their locations, complicating backup processes. A proposed convention suggests that applications should create a specific file within their cache directories to facilitate identification.
✦ Why It Matters
Implement a standardized file naming convention in your applications' cache directories to simplify backup processes.
Key Takeaways
- Adopt the CACHEDIR.TAG convention for cache directories.
- Ensure the tag file contains the correct header signature.
- Use the tag to automate exclusion from backup operations.
- Educate users about the purpose of cache directories.
How It Works
Applications create a CACHEDIR.TAG file in their cache directories, containing a specific header that identifies the directory as a cache. Backup tools can then recognize this tag and exclude the directory from backup operations, preventing unnecessary data transfer.
