Otava continues its business continuity series of videos on data backup and replication by explaining the different options when backing up your data.
Steven: There’s really a lot of options when it comes to backing up your data. You can back up to disk, you can back up to tape, you can backup locally, you can backup off-site. There’s even how many times a day do you want to backup?
There’s certain benefits to each of those options. If you want to backup locally and send your tapes off-site, you can do that but it’s a fairly time-intensive process. Generally, you work with a third-party provider like Iron Mountain to take tapes off-site. You have to remember to label those tapes, recall them; but it is an option if you want to push tape off-site. You can also backup locally to disk. What that gives you is it improves the speed because you’re writing to hard disk versus writing to tape. It will improve the speed of both the backup operation and it will improve the speed of both the restore operation.
You can also use this kind of disk-based backup off-site. If you have location A … Let’s say you have a Data Center 1, then you have Data Center 2. You can stream that data from Data Center 1 to Data Center 2 and have that written to disk across a fairly high speed Internet lane. What that does, it kind of gives you the best of both worlds. It allows you to transmit data off-site so it’s secure. That way, if something happens your primary location you have that benefit of getting it off-site but you also have the added benefit of writing it to disk. So, if you need to do a recovery, generally, it will be much faster than if you were to have to recall a tape from a third-party provider, mount the tape in your tape system and then do the restore.
