edd_t Posted June 29, 2006 Share Posted June 29, 2006 Currently at work and for the last 4 years, my backup solution has been SDLT 120/320. I have a MSL5026 tape library with 2 SDLT tape drives installed. At the moment I am backing up around 900gb every night, with compression i get it onto 6 SDLT tapes. It takes around 13 hours, which i know is pretty slow. Can anyone else suggest a newer faster technology with higher capacity tapes. I'm not up to speed with this sort of stuff at the moment Cheers, Edd.. Quote Link to comment Share on other sites More sharing options...
spackrackman Posted June 29, 2006 Share Posted June 29, 2006 900gb.. bloody hell.... who sits there and changes the tapes? maybe somekind of remote network hardrive storage would be more suitable for backing that much up. Quote Link to comment Share on other sites More sharing options...
edd_t Posted June 29, 2006 Author Share Posted June 29, 2006 lol thats what the robotic MSL library if for. great fun watching it pic tapes up and carry them to the drives and stuff. we have online backup for some data. but need a 2nd copy on tape which gets removed each evening and stored off site. and carrying 6 sdlt tapes every night in my bag is getting annoying.

carl0s Posted June 29, 2006 Share Posted June 29, 2006 Perhaps you could back up to a NAS box liek spackrackman says, and run the tape drive locally from there to reduce network congestion. As for type of drive.. hmm.. it'd have to be S-AIT or LTO I suppose. Can't you cut down the amount you're backing up? Quote Link to comment Share on other sites More sharing options...
Thorin Posted June 29, 2006 Share Posted June 29, 2006 Like carlos says, get some form of NAS box, then back up the NAS to an LTO drive. Or get the company to fork out for a SAN Quote Link to comment Share on other sites More sharing options...
Ark Posted June 29, 2006 Share Posted June 29, 2006 LTO tapes mate. http://en.wikipedia.org/wiki/Linear_Tape_Open Quote Link to comment Share on other sites More sharing options...
edd_t Posted June 29, 2006 Author Share Posted June 29, 2006 Dont really have to worry about network congestion as the company is closed most of the time the backups run, and it all runs on a seperate LAN using multihomed servers. 900GB is cut down!!! lol. Cool, I'll check out S-AIT and LTO tommorow, cheers Quote Link to comment Share on other sites More sharing options...
carl0s Posted June 29, 2006 Share Posted June 29, 2006 LTO tapes mate. http://en.wikipedia.org/wiki/Linear_Tape_Open 70MB/sec uncompressed performance - that's outrageous! That's over half a gigabit/sec needed from the network to feed the tape drive! Over 1gb/sec if it's compressing well. Quote Link to comment Share on other sites More sharing options...
Thorin Posted June 29, 2006 Share Posted June 29, 2006 that's maximum, you don't have to maintain that speed. Quote Link to comment Share on other sites More sharing options...
caliAl Posted June 29, 2006 Share Posted June 29, 2006 We have two 35Tb SANs which part of them are used for backups, plus we use LTO tapes for long term archive. Quote Link to comment Share on other sites More sharing options...
Ark Posted June 29, 2006 Share Posted June 29, 2006 that's maximum, you don't have to maintain that speed. Yeah you do. Less than gigabit local networks are for losers these days. Quote Link to comment Share on other sites More sharing options...
MKIVDreamer Posted June 29, 2006 Share Posted June 29, 2006 The natural upgrade will be to the MSL6030 bung a couple of Ultrium960 drives in there, jobs a good'un. The 960's take 800GB (compressed) cartridges, so depending on the type of data you're looking at 2-3 tapes per backup (I'm assuming full backup?) Theoretical max is 80MB/s per drive, although if you're streaming the data via a Windows server then you'll struggle to exceed 25MB/s in my experience. Should be able to backup ~900GB in a couple of hours (theoretically) Quote Link to comment Share on other sites More sharing options...
carl0s Posted June 29, 2006 Share Posted June 29, 2006 that's maximum, you don't have to maintain that speed. Well I know, but it'd be nice to get as close as possible. That customer of mine with the network problems is only managing 5MB/sec to his LTO-2. Quote Link to comment Share on other sites More sharing options...
edd_t Posted June 29, 2006 Author Share Posted June 29, 2006 cheers for all this guys. i'll look into all this tommorow when in work Quote Link to comment Share on other sites More sharing options...
