Hi all,

I've got a new HP DAT160 at home for backups. Connected in SCSI U2 LVD on my DS15A.

Is it officially supported on VMS 8.3 update 5 ?

The drive is recognized and I had no problems to init a tape, so I suppose it's OK. I don't plan to use compaction (My datas are mainly alreday compressed data). It will be nice to backup a 73 Gb disk on one tape...

For info, the DAT160 tape is thicker than others DATs. I now understand better how they manage to jump from 36/72 Gb to 80/160 Gb from DDS5 to DDS6 :-)

Gotta agree with Stephen here, the DLT's are much more reliable than the DAT tapes. I have a client that's always having problem with them. I've rarely had any issues with DLT.

Many of the Alpha support IDE disks, and as cheap as they are, disk-to-disk backup is very cheap and fast. I think John Malmberg got a VMS rsync client working that sounds promising. I've used rsync on other systems to do remote backups, and it's pretty neat.

I maintain my datas on two SCSI disks, and USB external disks on a PC (copy via ftp of zip archives and savesets backup). But I also made sometimes tape backups on DAT's; I have a DAT72 and a DAT160. Tapes are stored at office.

During the vacations, I keep my backups on DAT's and 2"1/2 USB disks (I have some smart 250 Gb ones). Some datas are also copied on DVD RW.

I have a very old DTL drive (a 6 Gb one) sitting somewhere

Twenty use per cartridge is OK for me, I generally use a tape 3 times max.

At work, main backup system is a SDLT320 library (on a Solaris system ... ). VMS backups are made on DAT 40 and DAT72 actually. No reliability problems.

At home, I had a DAT24 drive. No pb. I had a drive failure on a DAT72 (I have a new one now on the slim box).

The DAT160 is at least twice as fast than the DAT72. A 36,5 Gb backup was made
in 1h and 40 min which translates into a bit more than 6 Mb/sec , not bad.

The disk is a 73 Gb SCSI on on U169 bus and tje tape is on an Ultra 80 controller.

I recall that the disks failed on the public access VMS systems that included Fafner

At one time, didn't this web site have a job board? I would love to use my legacy skills one last time in my career.

Eisner, which is currently being moved, got an SSH update and the keys were updated to more modern encryption standards.
