I'm used to how it is at my college... they have this huge backup closet with backup tapes going back at least year...

now though, at this new compay im working for.. we are just cycling through 5 backup tapes.. one for each day of the week.. next wednesday, we'll rewrite over today's backup tape.

only 5 days?!

We have two months worth of daily backups(odd month, even month), one year worth of weekly back ups, 1 year of monthly backups and we keep our yearly backups forever.

EDIT: We use DLT IV and have 3 80GB tape drives. Each one is roughly 75% full every night.
 
these are compaq 35gig tapes.

i have no clue how much actually get backed up on them each day though.

they must be pretty expensive if all they could budget was one for each day and a spare.
 
not safe. DLT is considered pretty tough. When was the last time you dropped a HDD 6 feet to a solid floor and it was ok?

Amen to that. We use ARCserveIT here as well. Tried to do a restore on a file and the software didn't know whether it was coming or going. Took a couple of days to coax the file out.

Our backup schedule is like what ElectricAmish said - differential each night, weekends are full backups, once a month the tapes are taken off-site for permanent storage.

last thursday actually.. and it was more then 6.. 😛
 
ARCserveIT has been having issues ever since we joined teh company domain, which is global. Now tht we have multiple Exchange servers in the organization, it sometimes forgets where it is going and just stops backing up, but will still run. The only way to recover it is to reboot.
 
It'll probably vary a lot from place to place as you're seeing here. One thing I was amazed by in one of my grad school school courses on records management is how complex all the legal requirments for some of this stuff is. There's TONS of rules for various things although most companies don't follow a lot of the official (and legal) requirements. One of the companies I did an internship at though was VERY diligent on this (they had to be since they were a public utility company) and had an entire records management depart with all sorts of complex rules and procedures. I can't even remember now what everything was, but the general rule of thumb on most things (for them anyways) was 3 years of backups. After that a lot of things would be destroyed.
 
7 years, everything is redundant with data centers and sites in 10 states around the US.

Then again what else do you expect from a bank? There'd be millions of pissed off customers if we didn't keep their data (esp how much they owe us) safe 😀
 
backups? 😕

you mean like backing out of the parking lot?

i work with the field arm/offices of this company, not the "corporate" side, so backups are done 80's style, floppy disk :Q
 
Just last week I had to pull out the old 8" floppy backups from the mid 1970's to find information about a data file format. Just yesterday I got a call from someone that wanted to migrate their 25 year old data to something more current. Not only to you need to keep the backups forever you also need to keep a machine that can read those backups. Also I have had several people call in after trying to read their backups and find out they didn't have a backup. If you don't verify your backup you have only done half the job.
 
It's refreshing to hear that so many of you keep backups!

I work in tech support. Disaster recovery is my specialty. It's downright depressing the number of customers who have no backups.

TIP: Test your ability to restore your data. A backup that cannot be restored is useless. It constantly amazes me how many customers have made backups for years... and have no clue how to restore the data.
