Should I keep media after "BACKUP DATABASE PLUS ARCHIVELOG"?

Hi there,
If I do full backup like this ...
BACKUP DATABASE PLUS ARCHIVELOG
... do I have to keep copy of media (database files)? I am under impression that as long as my recovery window falls between "BACKUP DATABASE PLUS ARCHIVELOG" and NOW ... I don't have to keep media files.
Am I right or wrong?
Thanks to all answers!

Sure..if you don't need to restore back to one of the previous backups, then they are no longer needed.
Configuring a retention policy will handle this maintenance for you automatically.
However, some people will keep them around as a fall back if something should happen to their most recent backup. It depends on your paranoia level and amount of disk/tape space that you have.

Error in recovery after BACKUP DATABASE PLUS ARCHIVELOG

Hi,
With Oracle 9.2.0.6 on Unix Aix 5, I made:
rman ...
RUN
ALLOCATE CHANNEL disk1 DEVICE TYPE DISK FORMAT '/base/tempora/%U';
BACKUP DATABASE PLUS ARCHIVELOG;
Copy files from /base/tempora/% to another server in a directory with the same name.
Recreate the pfile and directory structure, and then
rman...
RUN
ALLOCATE CHANNEL disk1 DEVICE TYPE DISK FORMAT '/base/tempora/%U';
restore controlfile to '/base/rcterefo/oracle/o1_mf_19xw2mvb_.ctl';
restore controlfile from '/base/rcterefo/oracle/o1_mf_19xw2mvb_.ctl';
sql 'alter database mount';
restore database;
recover database;
sql 'alter database open resetlogs';
release channel disk1;
But rman fails at -> recover database; by asking an archive log 6 months old (and not in the backupset):
ORA-00279: change 1224563589 generated at 02/09/2006 16:29:46 needed for thread

Original base seems to works fine (can be stoped and restarted).
I thought that this BACKUP DATABASE PLUS ARCHIVELOG would contain in itself all the data needed to restart the database. Database has been stopped and restarted last week with no problem and I regularly do full backup with RMAN and TSM (we are testing now backups without TSM for a spacial case).
Has someone an idea of what's wrong?
Thanks

Hi,
Thanks for taking care of my problem.
When I try to do a set until sequence..., the RESTORE CONTROLFILE fails, telling it has nothing to restore. I think this is the same kind of problem I encounter with the full restore.
Aniway, the restore being good, i try to finish the recover and it fails, asking for a very old archive. Is it possible a transaction to be active after so much time?
In fact, I just decovered a file is in RECOVER status. I did an :
alter database datafile '...' offline drop;
since that, the recover is ok, from oracle (not rman):
recover database using backup controlfile until cancel;
Thanks again to everyone.
Regards.

Backup database plus archivelog

Even if you've switched your database to NOARCHIVELOG mode, the ArchiveLogs that were generated earlier are still "known" as they are still cataloged in the control file (a query on V$ARCHIVED_LOG would show them).
As you are running NOARCHIVELOG, you really do not need to do BACKUP DATABASE PLUS ARCHIVELOG;
Your backup would be in MOUNT but not OPEN state so there would be no transactions.
If you really want to "clear" those older archivelogs so that RMAN doesn't attempt to backup them, you need to run these commands in RMAN :
Crosscheck Archivelog All;
Delete Expired ArchiveLog All;The first command will verify the controlfile records against the files actually present on disk and mark as "Expired" all those they do not exist on disk. The second command will "delete" them in that RMAN will no longer look for them.

Hi
Run commands:

RMAN> DELETE NOPROMPT EXPIRED ARCHIVELOG ALL;
And then "backup database plus archivelog;"
Edited by: val75 on Apr 12, 2009 11:31 AM

After deleting expired archivelogs, backup is working fine...
RMAN>delete noprompt expired archivelog all;
RMAN>crosscheck archivelog all;
RMAN>backup database plus archivelog;
Actually, what is doing while issuing "crosscheck archivelog all" command????
thanks

Newbie.. is 'backup database plus archivelog...' needed?

On my Oracle 11.1, I'm performing full backup with command:
backup incremental level 0 database plus archivelog delete input tag LEVEL_0_INC;Since this database is not in flashback mode, I'm wondering is it needed to backup archivelogs together with datafiles?
could I done it without achivelogs and to delete them after that?

HT4060 ipad 4 - Should i keep charging after 100% ?

Should i keep my ipad 4 plug in even after 100%, just the way i do for laptop? As i charge my ipad twice daily from 40%, as my heavy usage is mainly on games that i play through wifi daily. and some streaming on it through my desktop pc.
right now i dont charge after 100% at all, but would it be alright and not damage my battery life!
And how long will my ipad 4 battery life will last and how to confirm how many cycle is left?

It will not damage the battery. The battery does not charge further at 100%

Backing up Database plus 48 hour achivelog

Hi!
I wanna create a script to backup all database files and archivelog with less than 48h (not interesting if they where previously backed up or not).
I am trying to run the folowing statement:
backup database plus archivelog from time 'SYSDATE-2' format 'E:\tmp\backup_%d_%u_%s';
But got the message:
RMAN-00558: error encountered while parsing input commands
RMAN-01009: syntax error: found "time": expecting one of: "tag"
RMAN-01007: at line 5 column 17 file: e:\tmp\backupbanco.rman
If i try the follow it works fine:
backup archivelog from time 'SYSDATE-2' format 'E:\tmp\backup_%d_%u_%s';
I think there is a stupid syntax error but i can't figure it out.
Can anyone give me a light?
Thx in advance!

OH no... Bad news! :(
Is there any alternative? It seems that:
backup database plus archivelog NOT BACKED UP SINCE TIME 'SYSDATE-2' format 'E:\tmp\database_%d_%u_%s';
Work runs ok but on the second day it will not back up again the data from previuos day...

Why Backup database then backup archivelog from time...

Dear Experts,
I found in one of our rman scripts the 2 following statements:
backup database;
backup archivelog from time 'SYSDATE -8';
It seems to me that a "backup database plus archivelog;" is more simple/accurate instead of these 2 lines as the retention windows is defined (5 days) for this DB so rman will manage the retention of datafiles and archived log, isn't it ?
Why this separate statement for the archivelog ? I find it redondant but is it...
Any advice is as usual greatly appreciated.
Best Regards,
Guillaume

You are right. The use of backup database plus archivelog; is much better and you are sure that you backup all archived log you need.
Probably that is an old script, previous version or the responsable of this script didn't know RMAN so good and the option you posted.
Bye, Aron

Is a Level 0 Incremental the same as Backup Database?

hi experts,
This is a 10g database running in archivelog mode.
This is the backup scheme I'm currently using:
backup database plus archivelog; (runs once per day)
backup incremental level 1 database; this runs every 3 hours
(All the incrementals I make are level 1.)
In another forum, I was advised to make a level 0 incremental backup, because you cannot restore a level 1 if there was no level 0 made earlier. Now, I'm looking for the RMAN expert's advice :-)
** If I do this will I have what I need to be able to restore: **
- backup incremental level 0 database; (this will run once per day)
- backup incremental level 1 database; (this will run every 3 hours
In other words, will I miss anything if I dont do a backup database ?
Thanks, John

If you taking level 1 backup and If you dont have any level 0 then RMAN take hole database backup (level 0) with level 1 command.
It is always advisible to take level 0 and follow the level 1.
I advise to see the below doc which covers all your doubts and best way to backup.
Hope this solves your issue.

10g rman database and archivelogs backup with multipled archlog destination

I would like to use the 10g database and archivelogs backup statetement
backup database plus archivelog;
I would like to restrict the location of the archivelogs backed out as I am multiplexing the
archivelogs
I did not find a LIKE statement and the backup database plus archivelog
Did i miss something
patrick boulay

I meant backup
I just want to restrict rman form backing up the two location using the 'one shot' 10g syntax
I used to backup using two steps
1) datafile
2) archlogs with a LIKE expression to tell Rman where to find the archlogs
1+2 with autobackup of control+spfile
the 'backup database plus archivelog ' syntax does accept a 'LIKE' expression

Backup Assistant Plus error won't go away.

Hello,
After Backup Assistant Plus was pushed to my phone i keep getting an application error:
Is there a way to disable Backup+ since i will probably never use it.
This is on a Samsung Stratosphere device.
Thanks,

Hi NickM219,
Application errors are no good! I know its important to have a properly working phone at all times. Let's get this resolved. If you are not going to use this great feature, you can remove it via MyVerizon http://bit.ly/xB4iTc .

Clip weirdness after Media Manager backup

Several of my clips have freaked out after the media manager backup. I'll have to go back to an autosave and see what exactly was on them, but definitely there was a modifed speed property and I think, a keyframed brightness filter.
Also had an issue with the burn, but once I get it redone, I'll check to see if there;s any other MM weirdness.
I'll have to re-edit the portions. What can i do to avoid this issue when backing up in the future, for speed modified, layered clips?

I feel for ya...
Let's say I was doing the Smith Wedding...2 cameras, 2 tapes each camera. And since I've maybe done 3 previous weddings with a total of 10 tapes used, I'll keep a dedicated naming convention for wedding tapes, (since I may do other type event work)...such as WED001, WED002, WED003...etc.
So for this project my REEL names will be:
WED011C1T1_Smithmmddyy
WED012C1T2_Smithmmddyy
WED013C2T1_Smithmmddyy
WED014C2T2_Smithmmddyy
Then for tape 1 from cam 1 (which has pre-event Broll and Interviews), I'd set in/outs for each clip with names like:
WED011C1T1_SmithBarbIntv
WED011C1T1_SmithBarbHouseExtBR
WED011C1T1_SmithJoeIntv
WED011C1T1BarbJoeKissBR
WED011C1T1JoeDogBitesMomNLaw
ect...down the tape, hitting 'Log Clip' after each In/Out is set and making sure that Reel and Clip are properly named.
Then rewind tape, select all logged clips in browser except JoeDogBitesMomNLaw (since I really won't use it), select File/Batch Capture and away it goes, while I get coffee and check up on Barb's Mom.
Put in second Cam1 tape, lather, rinse, repeat.
This way,
1 - You can be totally selective about which shots you actually capture (saving disk space)
2 - You can always come back and 'batch capture' the JoeDogBitesMomNLaw clip, when you realize you actually might use it after all.
3 - Since you probably didn't man both cameras, you've now had a chance to familiarize yourself with the shots the 2nd camera had.
4 - You can now color code shots w/o having to break them up from master clips.

After Flashback database can I use my backups?

I performed a flashback database and then opened the database with
alter database open resetlogs;
Now when I try the following command in rman I get this message:
RMAN> list backup

All the backups are still there but it tells me a new incarnation of the database has been registered in the recovery catalog.
My question is: Do I need to do anything different from now on? Also can my existing backups still be used if needed?
thanks in advance,
