We're running a SCO OpenServer 5.0.5 production box, with the following one-line scripts for (1) application system and (2) OS backups.
(1) find /u -depth -print | cpio -ocv > /dev/rStp0 -C10240 -K20000000
(2) find / -depth -print | cpio -ocv > /dev/rStp0 -C10240 -K20000000
According to SCO UNIX in a Nutshell, the -K value specifies volume size, but in what units? Blocks? Bytes?
I ran an OS backup this morning that captured 1,551,460 blocks.
The backup used to write to a QIC device with 250MB and 525MB tapes (I don't know whether the 250MB tapes were sufficient); now it writes to a DDS3 device with 12/24GB tapes (non-compressed/compressed). Do I still need to specify this parameter? If so, at what value?
