Full, Differential and log backup or Full and log backup? What to choose?
Hi All,
I have a SQL Server 2012 database of size <1 gb and the data of this db is expected to grow by 100 MB every month (i.e., ~ 1 gb per year). We have to backup this database to Azure Blob storage and data loss of 2 hrs. is accepted. Now can you please suggest
the best database backup policy. The option i have in mind are
1. Full database backup every week followed by differential backup every 2 hrs (or)
2. Full database backup every week followed by differential backup every day followed by transactional log backup every 2 hrs (or)
3. Full database backup every week followed by transactional log backup every 2 hrs
Note: My database is in Full recovery model
Well its bit difficult for us to tell what would be best for you as you only told RPO but did not tell us RTO. I mean in how much time, if disaster strikes, would you like database to be up and running. Backup policy would depend on that

Hi,
I was wondering if someone can help me. I have a MacBook Pro, it has came up saying I need to free up space on the disk as it full every time it starts up, so I log in and no icons or applications show up on the screen just my background wallpaper, the only thing I can do is the force quit keyboard shortcut but there is nothing to quit, I have tried to start up in safe mode but again there is no icons in the desktop,
I have my disks that came with my laptop I have went into disk utility to repair disk and I still seem to have the same problem .. No icons or apps or anything lol just the cursor I can only shut down the laptop via power but and the press shut down.
Please help I am going out my mind with this thing :(
Thanks x jadeThis can be used to boot the machine and delelte enough files to get it to boot normally.
.Create a data recovery/undelete external boot drive
Read about storage drive so you can store your extra stuff.
Most commonly used backup methods
Also here to see how a full boot drive slows the machine down
Why is my computer slow? -
How to do following restore? Full backup takes long and transaction backup in the middle.Thanks!
One database starts to run full backup at 10am. Full backup finishes at 11:45 AM
transaction log backups every 30 minutes: 10:00am, 10:30am,11:00 am , 11:30 am and 12:00 PM
At 1:30 PM
I need to restore database back to 12:00PM.
So I should restore:
1) Full backup at 10:00 am + transaction log backup 10:30am+ transaction log backup 11:00 am +transaction log backup at 11:30 am + transaction log backup at 12:00 PM
or
2) Full backup at 10:00 am + transaction log backup at 12:00PM
Because full backup starts at 10:00 am and ends at 11:45 am, I am not sure 1) or 2) should I choose.
Please let me know which one is correct--1) or 2) .Thanksalternatively you can make use of
RESTORE HEADERONLY FROM <BACKUP_DEVICE>
database backup has LSN number information in te backup header, and last LSN will help you to locate next log backup in
sequence to be restored.

Time machine full backup after disk and disk permissions repair
my macbook would not boot so i inserted the snow leopard DVD and did a disk repair and disk permissions repair, after that it booted perfectly but when it went to do a backup it did a full backup of 149GB , i am unsure why it has done this and would like to know how to stop it as i am trying to save space on my time capsule.
thank you in advanceBrycycle wrote:

I'm afraid you don't have much choice. You do have lot of space available, though.
Node requires deep traversal:/ reason:must scan subdirs|new event db|
No pre-backup thinning needed: 165.92 GB requested (including padding), 507.60 GB available
The "deep traversal" means TM compared everything on your system to the backups, and estimates that about 138 GB is new/changed (it adds 20% for workspace on the TM disk - the "padding" in the message).
If there's about 138 GB on your system, see #D3 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum), for some common reasons for TM to do a new full backup.
If there's more, #D4 there has some common reasons for large backups.
If all you did was repair disk and permissions, neither should have resulted.
the reason i did a permission repair and disk repair while running from the install disk was because my laptop would not boot from the internal disk so i did both just to be safe.
That's fine; just do the Permissions Repair again, while running normally. -
Can I create separate folders to save media on my Airport Time Capsule? Issue is I have a 256GB HDD Mac Pro Retina which is almost full. TC will only take backup of my HDD. So where would I save my photos and videos from my iPhone and iPad?
It is a hard one.. laptops with small drives are a pain.
What you need is a home media server.
Some people use a PC running itunes for cost.. but that is nothing like as good as using a Mac mini.. they make great little HTPC device.. you can plug in large hard disks and store all your files and media. And share it with the network.. Read up apple's instructions on home sharing.
https://www.apple.com/au/support/homesharing/
For cost you can buy a mini from 2011 or 2012.. I would not recommend earlier ones.. the advantage of 2012 is they have USB3 ports. But you will pay more for them.. new mini is not as useful.. they have soldered in memory and you cannot upgrade.. the old mini was the most easily modified mac in the whole range. Uses little power and can be bought for a $300US for a good one second hand.. maybe less. -
It seems that I must have the wrong settings in place but after going through my preferences, I could not find anything that gets rid of older backups. Its as if it is keeping every backup it ever made.

Thanks, I guess I always thought that Time Capsule did everything automatically and seamlessly.
Time Machine (the backup software) does, if it can, but that depends on the circumstances:
(A Time Capsule is a piece of Apple hardware combining a wireless router and hard drive.)
Effective with Snow Leopard (10.6), there's an option on the Time Machine Preferences > Options window to Notify after old backups are deleted. If that's checked, you might see this message when the disk is nearly full (we don't know just how close it has to be):
Once it is out of room and Time Machine has to delete old backups, it will send this message (after the deletions and new backup are done):
If you don't want to see that anymore, either check the Do not show... box or the Warn after ... box in TM Preferences. If you don't mind seeing it, just click OK.
If your backups fail with this one, the disk really is full, and TM can't delete enough backups to make room (it won't ever delete the last remaining one, though):
However, if you're on Leopard (10.5), the option is Warn when old backups are deleted and instead of deleting any backups, it sends this one:
Badly worded; all you have to do is remove the check from the box in TM Prefs > Options; then it will delete old backups as needed.

If I update from 10.6.8 to Mavericks and I have a time machine backup, can I do a full restore back to 10.6.8 and resume as if I had never updated if there is a problem? Probably an answer I should know but I don't. Thanks in advance! (instruction suggestions welcomed)
Upgrading the OS is a system wide thing. So all users will receive the upgrade.
It should not delete files and such. However, if you have for example files made with Pages '09. Then the new Pages that comes with Mavericks will make a copy of those files so you can continue to edit them. But those new files can not be opened in Pages '09. BUT again, some people perfer Pages '09 and they use that still. Mavericks will just hide Pages '09, it's still usable in Mavericks just hidden.
To be safe, make a back up of your system before doing any major upgrade.

I wanted to charge my iPod Touch 4G on my computer and i forgot that it automatically syncs which i didn't want it to. I cancelled the syn and when i checked my ipod it said the storage was almost full. I had 1.6GB before and it went to 46 MB?!? I just don't get it can someone help?
Connect the iPod to your computer and look at the storage used by the various categories as shown in the colored bargarph in iTunes.
Come back with the results.
An "other" larger than about 1 1/2 GB usually indicates that the "other" includes corrupted files. Usually restoring from backup eliminated the corrupted files. However, sometimes restoring to factory settings/new iPod is required.
To restore from backup see:
iOS: How to back up

Backup drive full and failing to back up
I've read the posts in an earlier thread that say what is supposed to happen:
http://discussions.apple.com/thread.jspa?threadID=1668180&tstart=45
I have 2 macs, one Intel iMac and one PowerMac G5.
On the Intel, TM tells me that it can't back up because the backup volume is full. Does that mean it does not know how to delete older backups?
On the G5, I am getting the message "Backup volume is read only" on some days and backup volume full on others. This is after 25 backups.
I don't want to eliminate files from the backup. Isn't TM supposed to be smart enough to make space for new incremental backups?Elkscat wrote:

yes, it's supposed to but TM is still very buggy and this is one of the bugs. when this happens there isn't much you can do. you can try manually deleting a few old backups to clear up some space and see if TM starts deleting old backups itself. this should be done from TM interface and not from finder. start TM, scroll to the backup you want to delete, click on the "gears" action button in finder's toolbar and select "delete backup".
If this doesn't help your only options are either getting a new drive for TM or reformatting the existing TM drive. -
My iPad is frozen with a message on the screen that says "iCloud backup is full" and it gives me the option of cancel or settings but will not go to either one or allow me to exit the message. How can I restart? It will not let me turn off or doesn't help to plug into computer
Try a reset:
Hold the Sleep and Home button down until you see the Apple logo.
Data will not be affected. -
I have paid and downloaded LION and want to update my IMAC, can i just run install and it keep photos settings etc from Snow Leopard or is a full reinstall with wiped hard drive, anyone have any experience of this and do i need to run a backup beforehand?
Always backup your important data before upgrading to a new Mac OS X.
Lion doesn't erase the drive but better to be safe than sorry.
And run Disk Utility (Applications/Utilities). Verify and if necessary repair the startup disk before upgrading.
Using Disk Utility to verify or repair disks
Before upgrading read here > Lion upgrade questions and answers: Apple Support Communities

Incremental and Full backups using WBADMIN and Task Scheduler in Server 2008 R2
I'd like to create an automated rotating schedule of backups using wbadmin and task scheduler, which would backup Bare Metal Recovery; System State; Drive C: and D: to a Network Share in a pattern like this:
Monday - Incremental, overwrite last Monday's
Tuesday - Incremental, overwrite last Tuesday's
Wednesday - Incremental, overwrite last Wednesday's
Thursday - Incremental, overwrite last Thursday's
Friday - Incremental overwrite last Friday's
Saturday - Full, overwrite last Saturday's
I need to use the wbadmin commands within the Task Scheduler and do not know any of the required Syntax to make sure everything goes smoothly, I do not want to do this through the CMD.I know each backup for the previous corresponding day will be replaced, how do you figure I wont be able to do incremental backups...
Because incremental backup is based on Volume Shadow Copy (VSS) feature and due to Windows Server 2008 R2 limitations (this limitation is resolved in Windows 8) only one version of backed up data can be stored in a shared folder. So the
result is that every time you back up some data on a shared folder, you actually creating a full backup of them.
is it not supported through task scheduler?
The Task Scheduler is only a feature that does the tasks that you have defined for it. Actually it runs the
wbadmin command that runs on an operating system with the mentioned limitation.
I know you can do Incremental backups through Windows Server Backup, but my limitation using that is I cant setup multiple backups.
Yes, you are right. Windows Server Backup feature in Windows Server 2008/2008 R2 has not this functionality (although
ntbackup in Windows XP and Windows Server 2003 had this functionality). So, the only workaround to this limitation is through using Task Scheduler feature with wbadmin command. For more information see the following article:
http://blogs.technet.com/b/filecab/archive/2009/04/13/customizing-windows-server-backup-schedule.aspx
So are you saying that even though I want each backup to go to a different place on the Shared Folder that it will replace the previous backup anyways?
No and because of this I said in my previous post that with some modifications and additions you can do the scenario. For example, you back up to a shared folder with the name of Shared1 on Mondays. You also have been configured the backup feature to back
up data on another shared folder, named Shared2, on Wednesday. When you repeat the backup operation in Shared1, only the backed up data that resides on it will be affected, and the data on Shared2 remains intact.

Hi R.Alikhani
Then do you know if wbadmin supports incremental backup in Windows 8? As you said the VSS issue is fixed in Win8. However, the wbadmin has less options then in windows server. I tried a bit but it seems it only supports full backup? ps, I use a network share
- will the incremental backup works if I define a ISCCI then? My remote backup PC is also running Win8. -
Backing up to a thumb drive - time machine doesn't delete older backups when it's full. I will have to erase and re-do the drive. Why?
You are both right.
Time Machine can backup FROM:
It cannot back up a USB thumb drive.
Time Machine can backup TO:
•A USB thumb drive (but most aren't large enough, and are very, very slow) -
I restored some files last night and now I can't access my backup and it's full.
Last night I was restoring some image files and everything appear to have gone as planned. The images were back and the time capsule continued to backup my system as before. I got up today and I keep getting a message that my backup is full and I also can't access my backup files. I'm not sure what went wrong. I am running snow leopard and have VMware to run win 7 as well. Any help would be greatly appreciated.
Some questions:
1) What was the volume (file size) of the restored image files?
2) What specifically happens when you try to access your backup files?
3) If you mount your Time Capsule's internal drive (presuming that's where Time Machine is writing its data), how much free space does it have?
By the way, as your problem seems to be specific to Time Machine and not to Time Capsule, I'd post future questions of this nature to the discussion section for your version of OS X.
