–Basic tips for Disk & Tape Backup/Recovery strategy.

--To be able to efficiently perform incremental backup check if "Change Block Tracking" is enable:
 SELECT * FROM V$BLOCK_CHANGE_TRACKING;

–If it doesn’t exist create it:
alter database enable block change tracking using file ‘+FRA1’;

# RMAN Format Description
###########################

%a Current database activation id
%A Zero-filled activation ID
%c The copy number of the backup piece within a set of duplexed backup pieces.bMaximum value is 256
%d Database name
%D Current day of the month from the Gregorian calendar in format DD
%e Archived log sequence number
%f Absolute file number
%F Combines the DBID, day, month, year, and sequence into a unique and repeatable generated name
%h Archived redo log thread number
%I DBID
%M Month in the Gregorian calendar in the format MM
%n Database name, padded on the right with x characters to a total length of eight characters
%N Tablespace name. Only valid when backing up datafiles as image copies.
%p Piece number within the backup set. This value starts at 1 for each backup set and is incremented by 1
 for each backup piece created. If a PROXY is specified, the %p variable must be included in the FORMAT
 string either explicitly or implicitly within %U.
%r Resetlogs ID
%s Backup set number. This number is a counter in the control file that is incremented for each backup set.
 The counter value starts at 1 and is unique for the lifetime of the control file. If you restore a backup
 control file, then duplicate values can result. CREATE CONTROLFILE initializes the counter at 1.
%S Zero-filled sequence number
%t Backup set time stamp, a 4-byte value derived as the number of seconds elapsed since a fixed reference time.
 The combination of %s and %t can be used to form a unique name for the backup set.
%T Year, month, and day in the Gregorian calendar in the format: YYYYMMDD
%u An 8-character name constituted by compressed representations of the backup set or image copy number and the
 time the backup set or image copy was created
%U A system-generated unique filename (default). %U is different for image copies and backup pieces.
 For a backup piece, %U is a shorthend for %u_%p_%c and guarantees uniqueness in generated backup filenames.
 For an image copy of a datafile, %U means the following: data-D-%d_id-%I_TS-%N_FNO-%f_%u

%Y Year in this format: YYYY

%% Percent (%) character. For example, %%Y translates to the string %Y
