Backups - 8mm Tape Drives
|
|
|
| Hi all,
How would I know if 2 tape drives are compatible? I mean if they are both 8mm, are they compatible or do they have their own proprietary write/read formats?
For example:

and
http://www.unylogix.com/data_storag....html#UND-40000
Also, do people mostly do their backups with tapes? Why not a USB 2.0 with a 400 MBps transfer rate? I'm using an Exabyte 8mm with 20GB capacity and 80GB data to backup. It's such a hassle to switch tapes in the morning and also slowing down the file server at office hours.
Thanks | |

But what would you be transferring it too? An external hard drive???
You should be scheduling your backups for non-production hours.
Also, what type of backups are you doing each night? Full backups every night (yikes!) or a normal backup at the beginning of the week and incremental the rest of the week? | |

| Yeah, I scheduled a Full on Fridays but by Monday morning it'll ask for another tape (takes 4 tapes altogether) and the rest of the backup job would be unforunately done during office hours.
I have about 80GB of data to backup. If I were to use an external USB 100GB, let's say, with USB 2.0 transfer rate I'll be done with a Full backup in about 4 minutes. | |

| The rate that you copy data is more dependent on what you are copying it to. USB 2 has a fast transfer rate but tapes or external hard drives don't have a write speed that is that fast.
However, you can backup the data from disk-to-disk, then disk-to-tape. Or your company will have to spring for a tape auto-loader. |
