LIGHTNINGAD Posted April 2, 2014 Report Share Posted April 2, 2014 i think i'm finally starting to get a handle on how Retrospect does its thing, but there is one thing i have noticed that has me baffled. When i set up my scripts, i decided to switch off compression as its going to slow things down, and backing up over 12TB a week is not quick! Once i get some extra hardware for speeding up the connections maybe i'll swicth it on... anyway, I have 5 separate scripts running each week, and then a second set of 5 running the next week. This lets me have a weekly rotation of LTO5 tapes that i can keep off site. For reasons i dont understand, In the Activities Window one of the scripts (and it just happens to be for the largest data set) is showing compression is ON. Yet if i check the script itself, its supposed to be OFF. All the scripts were written at the same time, and i checked that they all had compression off, so why is this one script behaving incorrectly?

Lennart_T Posted April 2, 2014 Report Share Posted April 2, 2014 There are two types of compression. 1) Compression in software. Valid only for disk media sets. 2) Compression in hardware. Valid only for tape media sets. I don't think you can turn off hardware compression. It takes place in the tap drive itself. It doesn't "tax" the CPU of the retrospect server at all. So take a look again at your settings and post back if what you see makes sense now. Quote Link to comment Share on other sites More sharing options...
LIGHTNINGAD Posted April 7, 2014 Author Report Share Posted April 7, 2014 Thanks Lennart, the only way around the problem was to reboot the mac! Once i did that it started to behave according to the settings i had entered in the script. Seems to be the standard cure for many of these little teething troubles i have had! regards Adam Quote Link to comment Share on other sites More sharing options...
