Offline backup via local portable SSDs and encrypted USB drives offers the advantage of being accessible without a network connection and not subject to cloud platform rules, but it carries the risk of damage or loss due to impacts. Google Drive and Dropbox offer convenient cross-device synchronization and ample storage space, but rely on a stable network for uploads and downloads. Using both backup channels in combination allows for daily cloud synchronization of work documents, weekly copying of photos and videos to the local hard drive, and the storage of additional off-site offline copies of documents and long-term project files. Monthly checks of backup folders verify file integrity, deletion of duplicate and redundant materials, encrypted storage of private files in the cloud, and regular cleanup of expired shared files to free up storage space.
