Oh I received this sms too.
So that's the reason they sent this sms.

if it is back in the days of LTO2-3 i think the HDD size is no where that huge as well, but nonetheless i doubt banks will ever go on storing data on HDD, there is a reason why they need to go on tapes, because of a 7 years archival purposes, imagine if they needed to store 7 years of data on HDD, how much would it cost compare to cartridges..

You'll be surprised how common lto3 - lto5 are still used nowadays

The other reason tapes are used is because of the infra. Its so much harder to extract info from tapes compared to hdd. Software aside, you just need a common usb port to access the hdd. But you need expensive specialized equipments to access the tape, hence the reason why tapes are considered "safer" compared to HDD

Tapes? 20 years out of date.

Banks are known to use outdated tech like mainframes and ultra low capacity hard drives like the IBM 3390.

So this is the real reason lar..   

Actually I asked that question before at another bank IT officer "Why banks still use magnetic tapes ah? Why don't you guys update a bit, like use hard drives? I mean, 1 external drive can easily store 1tb data, while tapes can only store like xxgb info"

He answered basically its the infra. You need to invest some serious $$$ on the infrastructure to extract info from the tape. You need to mount it to a tape server that uses proprietary software and other compilation programs plus other backup servers. External drives you only need a usb port, dah, cukup

Kinda makes sense what he said. Basically you can get your hands on the tapes but you can't extract the data so easily compared to usb ports

Yep. So many sohais.

The real IT experts here all laughing at them.

Nothing can beat tapes for offline backup.

Price per capacity is way cheaper than backup to disk.

Some enterprise did use disk to disk backup but they will have another layer that make a copy to tapes.

maybe LTO 5 tapes

It use LTO1, LTO3 or LTO5 tape..

Using magnetic tape for long time already..but now bank use hard disk (Datawarehouse) for security purpose..No more using LTO3 tape

Can google about the tape...Not like cassette or vhs one (shape) but yes use magnetic tape

Seriously if you guys are in enterprise IT field I really will facepalm .

oh ya, don't forget OUB and OCBC also.
