The question is - if I need to restore those files, can I use COPY instead of BACKUP?
Thank-you.
Solved! Go to Solution.

Re: Restoring from disk to disk
I would agree with both the posts.. i don't see any difference in doing either except for the reason highlighted...
Just a question.. do you folks think that there will be any real difference in terms of time taken to restore copy vs backup ?
I have done some tests previously and always found backup to be faster ? Any thoughts

Re: Restoring from disk to disk
File security on COPY:
a. _no_ SYSPRV _nor_ holding Resource Identifier equal to owner of directory: User doing COPY will be owner. If present, default ACL applies.
b. SYSPRV (or GRPPRV & grpUIC of user corresponds to target) or holder of said Ident:
b1. previous version of file exists: use security of that
if not:
b2. ACL on directory that specifies security with OPTIONS=DEFAULT: use that
if not:
b3: copy security of target directory.
A. Using BACKUP without /OWNER :
executing user becomes owner, users' processes' default protection used.
B. BACKUP with /OWN=PARENT :
copy security of target directory
C. BACKUP with /OWNER=ORIGINAL :
use original security.
---------
In COPY (without explicitly specifying version) next higher version is created.
in BACKUP, original version (even if lower) is created, unless specifying /NEW
--- ususally BACKUP/NEW /OWN=ORIG will be the desired result upon Restore; /NEW/OWN=PAR upon importing from somewhere else.
hth,
Proost.
Have one on me.

Re: Restoring from disk to disk
I already used copy instead backup to restore some files.

Re: Restoring from disk to disk
Anouther good reason mentioned is to keep the original owner_uic since these are database files.
I know I can use set file/owner command, but yet - why changing twice?
Thanks all.
