Yes, Google backs up to tape. I've seen it done and helped design the training for the process. As of 2019 it was a robust backup process with a pain in the butt restore process. It can and will be done, but it's not fast or easy.
- FrostKiwi 3y ago> As of 2019 it was a robust backup process with a pain in the butt restore process. Would love some more insight on this! Anything or any article you can share on how this is implemented at such scale?
- dbmnt 3y agoWhen I was there Google used multiple Sun/StorageTek tape libraries at each datacenter. The robots handled much of it, but there was still a lot of manual tape loading and unloading performed by technicians. Once tapes were full they were unloaded and hauled off to a secure third-party facility. They're still sold by Oracle, as far as I can tell: https://www.oracle.com/storage/tape-storage/#rc30p5 https://www.oracle.com/storage/tape-storage/#rc30p5
- saagarjha 3y agoThis is out of date; Google avoids tape exactly because the restore process sucks.
- dataflow 3y agoHow frequently do they back up to tape? (if this is something you can share)
- londons_explore 3y agoVaries by product. In general, it is a continuous process, and backups may not be 'point in time'.
