Implications of Restoring Operating System on Data Backup! - True Image Home 2012

Thread needs solution

I currently evaluating (30 day trial) True Image Home 2010.

What I cannot work out is the implication of restoring an image of my operating system, which is say several months old; specifically, on a back plan for data, with a schedule.

What I am thinking about, is say: Lets assume I have created a schedule to carry out a differential back up every day, at say 1800 hours. And this schedule has been running for 3, or 4 months.

What will happen, when I restore my operating system, from the image several months before!

Will Acronis, in the restored operating system, recognise the previous differential back ups of data, created by Acronis, prior to the restoration of the operating system!

Namely, does the Acronis program, in the restored operating system, examine the last differential back up of data, created, prior to restoration of the new operating system.

Any restore is based on which backup file is selected by the user to be restored. A restore can be either the single full backup; or it can be the single full plus a specific differential and the computer would assume the content that existed on the date of the differential. All prior data on the computer would be erased before the backup begins.

For example:
First full backup is Jan 1
Daily differentials for the next 30 days.

Now you need to restore the image.

If you choose the backup of the 15th, the first full Jan 1 backup will be restored plus the differential of the 15th. Two files would be restored and your system assume the same content as it had on the 15th.

Or, if you chose to restore the 30th, the first full Jan 1 backup would be restored plus the single differential of the 30th. Two files would be restored and your system would assume the same content as it had on the 30th.

I do strongly suggest that you do more frequent full backups as 100-150 differentials would be basing their foundation on the first full backup. If the full becomes corrupt, none of your backups are usable.

Any restore or any clone should be performed when booted from the TI Bootable Rescue CD.
After completion of either the restore or the clone, only the single main hard drive should be attached on first boot following the procedure. You do not want Windows to see two identical disks on first boot folloiwng the process.

Hi GroverH,

I am most grateful for your comprehensive reply, but must admit that I am more confused than ever! Possibly, because, I failed to address my question clearly!

I have been a user of Acronis TIH since it was first introduced in the UK, but because my previous PC was very limited, in terms of power (Processor, memory & Hard Drive, size), I only backed up the operating system. I never used Acronis to back up my data!

Because of the limited power of my previous PC, I never installed Acronis; I backed up my operating system using the Recovery CD ROM!

My practice has been to perform "Full Back-ups" of the operating system in stages.

Namely, a "Full Back Up" of the operating system, with just the software installed by the manufacturer; followed by additional "Full Back Ups" (Several - Not Differential) as I progressively installed software & drivers.

This allowed me to restore my operating system to any previous state! All back ups were stored on external drives.

Now that I have a modern, fast/powerful PC, I thought that I would trial Acronis TIH 2012, with it installed on my PC, and use it for backing up my data to two external USB 3 hard drives.

I would again carry out "Full Back ups (Not Differential) of my operating system, in the same progressive manner; again to these external drives!

So coming back to my question, which is based on the following Scenario:

(1) I install Acronis TIH 2012 and create a plan (schedule) to back up my data on the external drive, say at 7 pm every day.

(2) Before my PC has chance to implement the first scheduled data plan, I perform a "Full Back-Up" of my operating System (Call this Back-up "OpSys-A")!

(3) Let us assume, that my PC run satisfactorily for 21 days, and that 21 differential "Data" back ups have been created!

(4) On day 22, I discover that a corruption has occurred, and my PC fails to boot up!

(5) At this point, I decide to restore the Acronis back up of my operating system ("OpSys-A"), which I created 22 days before; specifically, using the recovery CD ROM.

The big question!

Will the restored operating system ("OpSys-A"):

(1) Recognise that 21 differential data back ups have been created, by the previous operating system!

(2) And create differential back-up 22

(3) Or will Acronis assume that this is a the first back up, and create a new Full back Up of my data

It would help me to understand the configuration of your system if you would post a screen capture of your system disk as it is displayed inside Windows Disk Management graphical view. This would enable me to see what partitions you have and how they are sequenced.

What version of Windows is in use and what type/make of computer?

Your first posting indicated you are testing a trial version of 2010. Did you mean to say you are testing a trial version of the 2012 version? You do indicate you have been using the 2010 CD for other backups.

A version of TrueImage does NOT need to be installed in order to create backups using the bootable media CD if you purchase the product. A version does need to be installed if you plan on using scheduling.

As for your questions, as I stated in post #1 any restore of your system will put the system back in time to the same condition it was as when you clicked "start a backup". At that point, the system knows about your past backup creation but the current backup has not been completed and the newly restored system will NOT know about the new backup differential 22. Therefore, after a restore, when the next backup is attempted, it will see the storage contents already has backup with the same number as it is contemplating and (most likely) will create a new full backup as the storage folder has contents different than what Acronis knew at the snapshot time the 22 was created. This is my opinion as I understand the procedure.

However, rather than have TI continue the current task with continuing backup numbers, you would be much much safer to cancel the old task and start a new task pointing to a new sub-folder with a new name. The Acronis data base does get confused between versions and folder contents. In my opinion, there is less confusion and less possibility of error or corruption if you keep the backups resulting from each task in its own folder or sub-folder.

Correct me if I am making the wrong assumption, but I am understanding that you have one task and that task is a "Disk & Partitions" type backup which has all partitions marked so that any and all partitions on your source disk are included in the backup.

TI makes its first full backup and all contents of the disk is included in the backup.
   Diff 1:The next backup of the same task is to make a differential backup and that backup will include any and all changes made on any partition within that disk since the full was created.
   Diff 2:The next backup of the same task is to make a differential backup and that backup will include any and all changes made on any partition within that disk since the full was created.
   Diff 3:The next backup of the same task is to make a differential backup and that backup will include any and all changes made on any partition within that disk since the full was created.
   Diff 4-22:The next backup of the same task is to make a differential backup and that backup will include any and all changes made on any partition within that disk since the full was created.

You use the term "Data" backups. Are you using that term to describe the changes that have occrurred on your disk between backups; or are you using "Data" to refer to the type "file backup" (personal files) which has nothing to do with the system files.

Within any backup plan, it is always important to have an alternate recovery procedure in case the primary procedure is not operative. This means some redundancy in how your have your data backed up. It is not wise to have all you recovery plans based on one specific full backup. One of my plan B's is to retain multiple full disk backups over an extended period of time.

Version 2012 Disk View--all partitions included in backup.

Below is one full plus mutlitple differential backups. User selectable for the 6 and 4 options shown.

Hi GroverH,

Thanks for your latest comments.

Yes, I made a mistake; I'm evaluating TIH 2012
By Data, I mean personal data (Photographs, Letters, E-mail, etc)

My system:

A desktop of UK manufacture (PC Specialist),
Windows 7 (64 bit),
A first generation i7 Processor,
12 GB of DDR3 RAM,
(1) Hard Drive 1, dedicated to the operating system (No personal data) 256GB
(2) Hard Drive 2, partitioned

(a) 100 GB (Used for the most recent Acronis back up of operating system)
(b) 1400 GB (Used for Personal data including Windows Live Mail)

Two 1.5 TB USB 3, external hard drives, which I have used for:

(1) Back ups of my operating system, using Acronis - several Full backups, at different stages of installing software/drivers (no incremental/differential backups)
(2) Back ups of my personal data; specifically, from the 1400 GB drive, 2(b) above! A full Back-up, with Differential Backups - All without compression!

The second external USB 3 hard drive is a duplicate, of the first (Belt & Braces)

At the moment, I use another propriety software for backing up my personal data, which works very well, but if Acronis TIH 2012, will perform equally well, I will use this.

With this other back-up software (away from home, and cannot recall its name), I can restore the latest "Index", which is a record of the the schedules/plans and status of previous back ups of my personal data.

Hence, after restoring an image of my operating system, all I need to do is restore the most recent index, and back-ups of personal data, continue, as if there had been no change to the operating system!

Thank you for the explanation. I would continue to use the same data backup. If you wish to use 2012 as an additional that would probably be ok but I would not drop any procedure that is working until you are 100% positive the replacement procedure has proven it will recovery as you would expect it to do.

Acronis has earned its merits as a system backup and recovery program. Only within the past few versions has it moved into the file backup arena. Most of the experienced users on this forum indicate they use differeing methods for their backups needs and do not put all their eggs in one basket--so to speak.
