A few simple practices could help save your digital data:

1. Keep many copies (software, databases, data, WARC files)  in different locations (local hard drives, Google Drive, Dropbox, etc.)
2. Use bagit to create checksums (digital fingerprint), monitor and replace the file with one of your backups when bagit reports bit corruption.
3. Migrate file formats, if and when file formats become obsolete.
4. Repeat steps 1 and 2.
