Knowing the robot and drives is all well and good but what software do they use?
We have comvault + sl8500 + lto3's in our place
Google's lost emails were apparently restored from Oracle StreamLine 8500 tape libraries using LTO drives. Up until now the tape infrastructure Google used to restore its lost emails has been unknown. Our understanding from informed industry sources is that Google has 16 StorageTek StreamLine 8500 tape libraries with both …
Avoid limits. Don't store your data on a windows box. Even if you have to let your users use windows.
Related to the backup solution. The Sun, now Oracle StorageTek jukeboxes are like the energizer bunny. They just keep working and never need to be kicked. We'd tried some other vendor jukeboxes to try and save cost, but they kept having issues, which kept causing backups to fail. Along with needing parts replaced.
In the context of this thread, who cares what backup software you use. I mean really, what's with the CommVault folks telling us they use CommVault and tape. For some organizations, tape can be a very cost effective means for storing backup data that does not have high RTO or RPO objectives. Disk plays a role, but to dump on tape like some EMC sales person is short sighted. RTO-RPO-TCO.
Let's put it in perspective - ONE 8550 - max config with LTO Gen 3 is 300,000 carts, 400 GB/cart – 120 PB. And that's up to 2,496 cartridge slots. Google has 16 of these. Let me know about that quote for 2000 PBs of disk.
The successful recovery from tape is really about backup management and tape quality. However, the ability to successfully manage a large disk and tape infrastructure like this on a daily basis is another matter.
So what type of backup software do you think is managing this size environment (not what type you use)? Custom or not?
