Note: VMS BACKUP question 5/29/87
Greetings to the Netlanders:
While working on VMS BACKUP command, I found a "surprise".
Accoding to the documentation,
$ backup/record input output
will record the current date on the backup date field of each file header.
$ Backup input/select=backup/backup output
Will do the incremental backup of those files dated equal to or later than
the last backup time of the file.
I tried the following procedure after a full backup with record qualifier
enabled and as I said was surprised. A lot of files that are not supposed
to be selected were in the output save set, i.e. no incremental effect was
noticed.
Could somebody tell me what is wrong in the procedure ?
$ m_d = "May28"
$ dev = "zfa0"
$ uic = "300006"
$ tgt = "''dev':[''uic'.save]"
$ backup/buffer=5/log/record/ignore=(interlock)/journal=bu.jnl -
'dev':['uic'...]/since=backup/backup/-
excl=(j.*,*.tmp,*.jnk,junk.*,*.log,*.jnl,*.bck) -
'tgt''m_d'.bck/save/owner=original/label='m_d'I
P.S. After I ran this procedure, I found, instead of the backup date field,
the REVISED DATE field was changed.
