Backup with Pax command. How to verify tape?
Dear all experts online,
In my environment of AIX 5300-07, I am currently using "pax" command to backup all filesystems that I need to backup and it will take me around 4 hours time with LTO3 tape drive.
When I need to verify the tape after backup, I am using "pax" command to list all files in the tape and it also cost me 4 hours time as well.
Is there any other way to verify the tape with a shorter time taken?
The using of "pax" command is due to there are a lot of single files are exceeded 10GB file size and I can't use "tar" for this kind of files.
Backup :
pax -wvf /dev/rmt0 './data01' './data02' './data03'
Verifying Tape :
pax -vf /dev/rmt0
Thanks.
