I have a client who would like to migrate data to a "long-term" storage media.
Basically, the client has legal documents that, they are required to keep for up to 30 years.
The client would like to copy data by year to a backup/storage media and put into a firesafe for the next 30 years. If they ever need the data back, pull the tape out of the firesafe and restore it.
Does anyone have recommendations about archival backups for mission-critical data (that is required by law to keep up to 30 years)?
