good morning
i try to use mt / tar commands to backup several new servers (Ubuntu
18.04 LTS, kernel 4.15.0-112-generic, Dell T630 and 640) on their LTO6
tape drives.
i try to log my backed-up files with block count, to make file restoring
faster ('tar --block-number').
Thus, i've activated the 'mt stoptions scsi2logical' to activate block
count.
Then, when i change the 'mt setblk' option on the same server, the
number of saved blocks increases or decreases ('mt eod' + 'mt tell') -> OK
But when i change neither the 'tar -b', nor the 'tar --record-size'
options, block count on my tar log file is still the same. No
compression activated.
Anything wrong with tar block count ?
thanks
