Weekly? Daily? backups

I have some possibly dumb questions about Time Machine. My weekly backups, which go back to May, 2008, are always from a Friday. Is a weekly backup simply one of the daily backups from that week? Which one? Or does it somehow incorporate file changes from all daily backups from that week?
Why Friday? Are everyone's weekly backups done on Friday, or is that because my first one was on a Friday (I don't know if it was, but maybe).
Similarly, is a daily backup simply one of the hourly backups? If so, which one? The last one of the day, or ?
Thus, if I create a file on Tuesday and delete it on Thursday, will it "miss" my weekly backup? If I leave it there over the weekend then will it be included?
I often use TM as a casual archiving system. Serious files get saved in other ways, and I use SuperDuper as well. But sometimes I just want to have TM contain certain things for easy retrieval.

Yes.
Which one?
The first of the day.

Not exactly. Each backup is, in effect, a full backup. I know that seems odd, but it's true. See [How Time Machine works its Magic|http://web.me.com/pondini/Time_Machine/Works.html] for an explanation. When Time Machine "thins" expired backups, it simply deletes them. But each remaining one is still a full "snapshot" as of the date & time of the backup.
Why Friday? Are everyone's weekly backups done on Friday
No. And there's nothing special about a weekly backup, other than being kept longer.
is that because my first one was on a Friday (I don't know if it was, but maybe).
Yup. Mine are Thursdays.
Similarly, is a daily backup simply one of the hourly backups?
Yes.
If so, which one? The last one of the day, or ?
The first of the day.
Thus, if I create a file on Tuesday and delete it on Thursday, will it "miss" my weekly backup?
Yes. The first backups of Wednesday and Thursday will be kept for a month; then deleted.
If I leave it there over the weekend then will it be included?
Yes, the first backup of the week will be kept as long as there's room on the drive.
I often use TM as a casual archiving system. Serious files get saved in other ways, and I use SuperDuper as well. But sometimes I just want to have TM contain certain things for easy retrieval.
Yes, that's exactly what it's designed to do. So the backups of anything that was on your system for at least 24 hours will be kept for at least a month; anything that was on your system for at least a week will be kept as long as there's room.

RMAN MONTHLY/WEEKLY/DAILY backups

Hi,
Using RMAN how can I schedule MONTHLY/WEEKLY/DAILY backups.
We are using TIVOLI for our backups.
I want to keep the monthly/weekly backups in seperate tapes so that I can use later.
Thanks in advance.

Hi,
You will nedd to create 3 RMAN backups using TAGs and congifure Tivoli to put MONTHLY/WEEKLY/DAILY backup on different tapes using the TAGs that you created.
Example of backups:
DAILY
run{
allocate channel t1 device type sbt_tape parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo_SID.opt)';
allocate channel t2 device type sbt_tape parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo_SID.opt)';
backup
incremental level 1
format 'BKP_HOT_DAILY_SID_%U'
database
tag 'DAILY_SID';
backup current controlfile format 'BKP_CTL_DAILY_SID_%U';
WEEKLY
run{
allocate channel t1 device type sbt_tape parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo_SID.opt)';
allocate channel t2 device type sbt_tape parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo_SID.opt)';
backup
incremental level 0
format 'BKP_HOT_WEEKLY_SID_%U'
database
tag 'WEEKLY_SID';
backup current controlfile format 'BKP_CTL_WEEKLY_SID_%U';
MONTHLY
run{
allocate channel t1 device type sbt_tape parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo_SID.opt)';
allocate channel t2 device type sbt_tape parms 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo_SID.opt)';
backup
incremental level 0
format 'BKP_HOT_MONTHLY_SID_%U'
database
tag 'MONTHLY_SID' keep forever logs;
backup current controlfile format 'BKP_CTL_MONTHLY_SID_%U';

Require backup script which deletes the daily backups after weekly backup

Hi,
I am new to Oracle administration. I require a backup script which will delete the daily backups (incremental) after weekly backup is taken (full database backup).
Currently I use Oracle 10g for one of my production server.
My backup strategy is given below.
I would like to take full database backup weekly(online). To be precise, on Saturday.
I need to have daily incremental backup and they should get deleted on Saturday after the weekly full database backup is taken.
Also I would like to keep 4 weeks full backups. After that one by one we need to delete the backup.
For example, if I have 4 weeks fullbackup of February, after taking full backup for first week of March, the backup of first week of February should get deleted.
Kindly help with your suggestions.
Thanks & Regards,
Rafnas

Hi,
Thank you for pointing to the blog. It was very much useful.
I was testing the backup strategy using your script. It worked fine for first set of daily backups.
After weekly backup is taken, the daily backup script fails for taking the backup from next day onwards.
It gives the following error stack.
Starting backup at 05-MAR-09
using channel ORA_DISK_1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of backup command at 03/05/2009 01:47:55
ORA-01455: converting column overflows integer datatype
Could you please let me know why integer datatype comes into picture while taking backup?
Please advice.
Thanks & Regards,
Rafnas

How do TM daily backups transition to weekly backups ?

How do TM daily backups transition to weekly backups is something I'm trying to figure out.
As of Saturday Dec 1 at 0000 hrs I had daily backups for
Oct 28
I had none for Oct 29, 30 and 31
Nov 1, 2, 3, 4, 5 and 6
I had none for Nov 7 thru 14
Nov 15 thru 30
I've been tracking this info on an hourly basis via a crontab entry setup using CronniX.
When TM did its hourly backup on Sat Dec 1 at around 0030 hours the Nov 1 daily backup was removed with TM reporting it had expired.
When TM did its hourly backup on Sun Dec 2 at 0032 hours the Nov 2 daily backup was removed with TM reporting it had expired.
Note that the Oct 28 backup is not being deleted/expired.
At this rate from now on I'm wondering just how many of my November daily backups will get removed by TM is the wee hours of the morning at around 0030 hours!
What I'm really curious to see is how TM designates a weekly backup.
Has anyone seen a TM weekly backup show up yet and if so how is it labelled on the TM backup Volume and in the TM browser's date/time tick marks located vertical on the right had side ?
Thanks....

My thoughts on this at this time is that the Oct 28 daily backup contains all the necessary backup data that was contained in the Nov 1 and Nov 2 backups so therefore TM can expire/delete them with impunity. It will do this with the Nov 3, 4, 5, 6, etc until it finds some backed up daily data that does not exist in the Oct 28 backup. We will see as time moved forward.

TS4585 I got this message on my ipad "This iPad hasn't been backed up in 2 weeks. Backups happen when this iPad is plugged in, locked, and connected to Wi-Fi.

I have this message on my iPad and the device hungs. I cannot do anything with it, including powering off.
"This Ipad hasn't been backed up in 2 weeks. Backups happens when this Ipad is plugged in, locked, and connected to Wi-Fi."
Does anyone have an idea how to solve this problem?
Many thanks/Jeremy

The system error basically should lead to the culprit of your issue. iCloud will ONLY automatically back-up to the cloud if all of the following are met:
1) iDevice is plugged in to the wall outlet/power source.
2) iDevice is connected to a WiFi network; iCloud does not back up over 3G/DATA networks to limit the data caps on most carries nowadays.
3) iDevice has been locked and innactive - usually takes place when one is sleeping.
Make sure all three of these are in fact in effect. If you are noticing that it has gone 2+ weeks unable to backup automatically, I would recommend navigating to the iCloud settings panel on your iPad.
Tap on Settings -> iCloud
On this screen I would advise for you to scroll all the way to the bottom and selete Delete Account.
*THIS WILL NOT DELETE YOUR BACKUPS, JUST REMOVE THE ACCOUNT ASSOCIATION FROM YOUR iPAD**
After this has gone through, sign back into iCloud and manually do a backup by selecting Storage & Backup and scrolling down to select the Back Up Now option. Once this is complete, use your iPad as you would. Over the course of the next few days, go back to where that Back Up Now option was and below it you will see when the last backup was done. This should be changing almost daily if the mentioned measures earlie in my response have been met.
Should this not solve your problem then due let me know. But to my knowledge, this has solved my iCloud issues with my iPhone 4S and my iPhone 5.

Daily Backup too large

Hello,
I ran my Time Machine backups since Saturday (Full Backup) and daily backups (manualy). Today I know that I only made about 300MB of changes on my work files and now Time Machine is backing up since one hour with over 21GB of data.
Why? When this will go on like this, I can buy a new Drive next week.
May it be possible that these 21GB are the changes of my Leopard update to 10.5.7? Thats the only thing I can think of. But I did this update yesterday and not today - so why is Time Machine backing it up now?
Thanks for any hint.
Ps. I have a Lacie 2big Network drive connected to my router.

Have you tried either the +Time Tracker+ or +Backup Loupe+ apps, per previous posts in this thread, to see what's taking up the space?
Yeah. Backup Loupe came through for me and for some reason my Thunderbird E-mail system was eating up gigs and gigs at a time.
Ah, yes, Thunderbird is one of the common causes of big backups. It keeps all your emails in a single file (or database), so when you send or receive a single tiny email, the whole thing is changed and must be backed-up in full again.
Suffice to say I excluded thunderbird's library. I also ended up wiping the backup volume clean and starting fresh. I've only had two backups since then, but if Backup Loupe's any indication excluding thunderbird along with the other exclusions seems to have done the trick.
Many folks copy the Tbird file to another, that's not excluded, once a day or so, to be sure it does get backed-up. This can even be automated, via an Applescript or Automator.
Or you could use CarbonCopyCloner, SuperDuper!, or the like, to back-up the file periodically. Those are most often used to make full "bootable clones" (which many of us do in addition to Time Machine), but can do this sort of thing as well. CCC is donationware, so you can try it before you buy it; and while SD has a free version, I think you need the paid one (about $30) to do this.

Co-location for daily backup

I have created a protection group for file server and taking backup of a share on tape drive.
under protection method--> I chose I want short-term protection using : tape
retention range: 1 week
frequency of backup: daily
backup mode: full and incremental
so full backup on Saturday and other days incremental backup.
I have around 700 GB data size.
I have shortages of tape. from recovery option: I saw in this month on 12thOct, on Saturday it run full backup. It took one tape [say tape 1]
on the next 6 days it run incremental backup on another tape.[say tape 2]
again on Saturday for full backup it took tape 3 [tape 3]
again to run incremental backup it is asking for free tape. and back up failed.
in this way I am wasting space on tape. data size is 700 GB, tape size is around 3 TB.
I can see there is option in 'optimize usage' where I can mention under advanced. write period and expiry tolerance.
i believe I need to modify these settings. please suggest if i want daily incremental backup and full backup on Saturday with 1 week retention and reuse the same tape or second tape instead of waiting for more tapes

Hi,
It is currently working as designed for tape library.
See the following TechNet page:
How DPM Uses Tape Libraries
http://technet.microsoft.com/en-us/library/hh757885.aspx
Short-term tape "full and incremental" option
The full backup will require a free tape for each scheduled job, and the incremental backup for all data sources will be appended to a single separate tape.
As tapes fill up, new free tapes will be allocated.
When the next full backup occurs, it will require another free tape, and subsequent incremental backups will be appended to another free tape.
So basically, you will need three sets of tapes for a 1 week retention range.

Accessing Time Machine Daily Backups

I am trying to restore a file a week old. The scale on the right of Time Machine goes back to April 2009, which indeed when I set it up. But the tick marks for daily backups are grayed on the scale and I can't seem to access them. The hourly backups are fine. (BTW, I noticed that daily backups are grayed in one of apple's documentation screenshots, too). I have a 5G Time Capsule, which is only half full, and I have never got any message that early backups are being deleted. I think I am being stupid, but I am stumped.

First, Time Machine does "thin" current backups:
Your very first backup, and the first backup of the same day of each week is kept for as long as there's room.
The first backup of each other day is kept for a month; all others are kept for 24 hours.
You'll only get a message when TM is deleting the oldest weeklies to make room for new ones.
Most likely, what you're seeing with the grayed-out backups is, what you see in Time Machine may depend on how you get there. Start with a Finder window pointed to your home folder, and with both a sidebar and toolbar; then +Enter Time Machine+ and see if the other backups are there.
If, for example, you're starting from Mail, with a fairly new mailbox selected, and +Enter Time Machine,+ only those backups made since that mailbox was created will be shown; earlier backups will be grayed-out.
If that doesn't help, try #E2 in the Time Machine - Troubleshooting *User Tip* at the top of this forum.

Schedule the daily backup from Monday to Saturday?

Dear all,
I am the first time to scheduling the daily backup, I have following questions:
1) My daily backup scripts in what format? for example: in sh format
Run
     CONFIGURE CONTROLFILE AUTOBACKUP ON;
     CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
     allocate channel ch1 type disk format '/u02/db/backup/RMAN/backup_%d_%t_%s_%p_%U.bck';
     backup incremental level 1 cumulative database plus archivelog delete all input;
     delete noprompt obsolete;
     delete noprompt archivelog all backed up 2 times to disk;
     backup current controlfile;
     backup spfile;
     release channel ch1;
2) I am not familiar with to using schedule job, I know following structure.
Minute hour [Day of Month] [Month] [Day of Week]
Minute (0)
Hour (24)
Day of month (??)
Month (every month)
Day of week (0-6) 0 = Sunday, 1 = Monday, ... or Sun, Mon, etc)
Command to execute (how to execute the command)
Best Regards,
Amy

Hi,
Firstly, if you are using recovery catalog, then create rman scripts and In case you dont have recobery catalog, then add the backup script in the .sh file .
Then create .sh file and not to forget add environment variable for oracle in that .sh file.
Then schedule that file with cron and format you know for the cron.
Make sure cron is started on the machine.
Example for .sh file is
export ORACLE_SID=<ORACLE_SID>
export path=<ORACLE_PATH>
rman<<EOF
connect target sys/<password
run{
body
but the best way is to go for rman backup scripts using recobery catalog

Time Machine making Daily backups of Entire Itunes Library

Hi There,
I have searched around the forums and cannot find an answer to my problem.
I am using time machine over a 1TB time capsule, my laptop is the only computer that is backing up to the drive,
Originally I noticed that my time machine backups were taking a long time (over 7 hours while connected through Ethernet)
I have downloaded BackupLoupe and using this utility I have found that daily backups of my entire Itunes music Library are being made (122GB).
Does anyone have any idea what may be causing this issue? I have followed the Time machine trouble shooting guide and Completely wiped the drive and started again,
I have performed a disk and permission repair on both the time capsule drive and on the Macbook through the install DVD, however each time I initiate time machine on the freshly reconditioned drives it happens again.
Any help would be greatly appreciated, I am going slowly insane.
Cheers
Josh

Is it only the iTunes folder; and the entire contents?
If so, the iTunes folder itself may be damaged. That happens occasionally; something in a folder object gets corrupted, and Time Machine either doesn't find real changes, or thinks everything changed.
In those cases, the only solution we've been able to find is to rename the folder, create a new one, move the contents, and delete the old one. The first backup afterwards will back up everything, but thereafter it should be ok.
