hello all,
I have created a script for taking a full backup together with archive logs using RMAN.
Now I wish to take differential backup as well.
How do I do that? Is there any command from RMAN to take differential backup such us
RMAN> backup database with differential;
thanks

I have tried :
RMAN> backup database with differential;
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00558: error encountered while parsing input commands
RMAN-01005: syntax error: found "identifier": expecting one of: "archivelog, backup, backupset, channel, controlfilecopy, current, database, datafile, datafilecopy, delete, diskratio, filesperset, format, force, include, keep, (, maxsetsize, noexclude, nokeep, not, parms, pool, plus, ;, skip, spfile, setsize, tablespace, tag"
RMAN-01008: the bad identifier was: with
RMAN-01007: at line 1 column 17 file: standard input
WITH is not correct.
Does anyone knows the syntax of this command?

By having the above backups all the archivelogs after the backup will be deleted.
What about when I will need to do a restore, don't I need the archivelogs as well.

Something else, If you take a incremental backup level 0 and level 1 how do your restore is it like:
RMAN> shutdown immediate;
RMAN> startup mount;
RMAN> restore database;
Will that is correct or you need to restore from a incremental backup?
thank you

Did you read the whole topic before posting this answer?
Obviously not otherwise you would understand that I didn't say that this command exists but just implies that OP should refer to the documentation which he did and found himself the answer.
Regards
Michel
