Then you do archival of data no longer needed for production work but needed for compliance/contractual obligations from your primary datacenter(s) to tape for those 5+ year retention. Use your favorite flavor of disk-based backup onsite, with another copy either in another internal site or cloud but only for that short term (60-90 days) where 99% of actual restores are done (strongly recommend using immutable for that 2nd offsite copy). Iron Mountain) for ARCHIVAL storage, not short-term backups.
What people need to consider, IMO, is using tape media stored in a secure offsite location (i.e. None of these problems exist with disk backups. You're going to have to find and buy a tape drive to restore your tapes when your office gets nuked. If you aren't keeping a fresh tape drive with your tapes you're backing up. Why add another day or two to your downtime in the event you need to do a restore? Sure it's great to understand how they work if you ever need them, but they're barely a viable option anymore in my opinion. I don't brag about my years of using tape backups on my resume. I don't get hired based on the mainframe experience I got in college. I'd say they don't have outdated technical proficiency. That means slower to to backup, slower to restore, slower to test if it's a viable, recoverable backup.Īs a 53 year old with 31 years in IT, I think tapes are shit in most cases, part of the reason is because they're harder to use by people who don't know "true disaster recovery" as you call it. £100 worth of tapes is all I need to recover from a nuke dropped over my city, is there anything else better/safer/cheaper out there that I am missing? So here is my question, if tapes are apparently so untrendy, how do you airgap your backups? I asked that and usually I hear about how old and outdated technology it is, how nobody uses it anymore, but when I ask in response how else can you airgap your backup and have multiple copies of it, I never get a straight answer. Usually when I talk with other fellow IT sysadmins, or MSPs about this strategy they are usually impressed until I touch the tapes subject, then I usually get smirk as a reaction. Quarterly go off-site to company's office in a different city. On top of that, we also do weekly, monthly, quarterly, and annual backups onto LTO6/7 tapes which go to two separate fire-proof safes.
First copy goes on two NASes in one building, and backup copy job goes onto single larger NAS in another separate building.
