tape max speed

[kubimike]

does veeam in any way limit the speed as to which it can read/write to tape? Looking to move on to LTO7 and its seems pretty quick. I am at LTO5 with an HP MSL2024 writing at roughly 70MB/s. Want a tape drive that can hit 150MB/s

The speed of file to tape or backup to tape job is mostly defined by read speed provided by backup repository, speed of repo-to-tape device connection, write speed provided by tape device. We don't put any cap on the later, but keep in mind all three variables (not just a single one) while thinking about performance improvement. Thanks.

Sure, as it reads from the repo it has to re-hyrdate anything if you're using cloning .. I thought of that after I posted this however. Im going to use the HP L&TT tool to do a speed test on my tape drive w/o compression to see how it fairs.

LTO 7 drive with LTO 7 7 tape, local disk as source backup speed 303 MBS
LTO 7 drive with LTO6 tape Local disk as source backup - speed 153MBS

LTO 4 driveLTO4 tape local or remote server 53MBS

This is with veeam or a testing tool ? Thanks!
