Anyone considering backups for archival purposes MUST have periodic rereading/migrations setup - in order to verify the media's integrity as much as the drives - and ensure that when new technology is obtained, enough overlap is left to allow old data to be moved to the new media. Technology such as LTO is guaranteed read/write for one generation backwards and read-only for two. LTO4 cannot read LTO1, LTO5 will not be able to read LTO2. This makes the "update!" pressure at least a little less extreme... I would not trust hard drives for long term cold storage. My experience is that they tend to fail to spin up after a few years. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
