Most likely, Your backup storage device is configured as a File system Fat32 which has a limit on the sizes of individual files. This limit caused your full backup to be split into pieces.

If you want your backup to be one large file, you will need to convert your storage disk to an NTFS file system. Do a google search on "convert fat32 to NTFS"

Incremental backup type.
Basically an inc tracks the changes since the last incremental
Backup 1 is a full backup
Backup 2 records the changes that has occurred since Backup 1
Backup 3 records the changes that have occurred since Backup 2, etc

Differential backup type
Basically an diff tracks all changes since the last FULL backup
Backup 1 is a full backup
Backup 2 records the changes that has occurred since last full
Backup 3 records the changes that have occurred since last full
Each diff keeps getting larger in size as each diff tracks all changes since the last full backup.

To restore/recover a dif backup, you need the full plus any diff.
To restore/recover an inc backup, you need the full plus ALL inc counting back to the full

If using the Diff method and your wanted to restore Backup #10, you would need two files (Full plus #10).
If using the Inc method , you would need the full plus all 10 files . If one inc gets corrupt or deleted, such as Inc #4, then inc backups 5,6,7, 8, 9, 10 are of no value as the links in the chain are no longer sequential.

Thank you.
You are correct in saying , that my storage device is 64 GB usb pen drive. and has FAT file system FAT32.

I don't know whether and how it has a limit on the sizes of individual files caused full backup to be split into pieces. I did not set any limit ???

As you told that the full backup has split into pieces That means i cannot delete any version from v1 to v9 as shown in the image !

How did you find out that it is full backup split into pieces ?

I still do not understand this !
Can you explain the image , i.e. ST3160316AS_full_b1_s1_v1
ST3160316AS_full_b1_s1_v2
ST3160316AS_full_b1_s1_v3
.........
and so on.

I want to know whether ST3160316AS_full_b1_s1_v1 is full backup or not ?

or, ST3160316AS_full_b1_s1_v2
ST3160316AS_full_b1_s1_v3
....... are also part splits of single full backup ?

2. Now when I go for Disk & Partition Backup menu in ATI 2013, then in Configure Disk Backup Process, there are three things :
i) Source - clear

ii) Destination - clear

iii) SCHEDULE --not understood

i HAVE attached the of the default schedule settings image that appears, please have a look.

Under this , Backup Scheme : It says Incremental

Is it default ??? , i think , because i have not set any setting.

If it is default then i think it suppports my query regarding different versions v1 to v9 .

That there are 9 versions of single full backup in the first image i provided / attached !!!

I am correct or not ???

You have said same here !!

Incremental backup type.
Basically an inc tracks the changes since the last incremental
Backup 1 is a full backup
Backup 2 records the changes that has occurred since Backup 1
Backup 3 records the changes that have occurred since Backup 2, etc

But the Backup image containing different versions V1 to V9 were made in single Backup Process/ time . So i don;t understand if it is incremental then how Backup 2 records the changes that has occurred since Backup 1.

Will post in a few hours. I had to stop now.

While Grover has a rest :) .... The reasons those files are split (and True Image does that automatically) is because a FAT32 formatted disk has a maximum file size of 4GB, so True Image will split the file up into 4GB slices, 4194304KB = 4.194GB.

V1 to V9 are the split of images to make your one full, they will all be needed to make a recovery. In other words what you have is.

Full image = Image part 1, image part 2, image part 3 etc.

The default image type is incremental. If the task has not bee run before, TI 2013 will automatically make a complete disk image (a Full) and then make incremental images.

For help in understanding the 2012 backup, click on Link #2 inside my signature below. Figures 11-Full; 11-Inc; 11-Dif illustrates some examples of setting. It is best not to use the default settings but create you own such as listed in the figures 11 examples.

The FAT32 is a file size limit set by the Windows program. User cannot bypass this limit. If you do NOT want the limit and want the backup file to be one large file, you will need to "convert" the FAT32 drive to an NTFS file system.

No, you can not delete any pieces (v1-v9) or none will be usable.

.
and so on.

This is one backup file divided into 3 pieces. all pieces required for validity. It is the "s1" and the "V1, V2, V3" which tells me it is one file broken into pieces. It would read like below if it were 3 backups of the same task. .
b1_s1_v1
b1_s2_v1
b1_s3_v1
A different task would read differently.

This is One backup split in to pieces. The date-time listed in the storage file folder can help you to understand as the date will be the same and the time very similar.
ST3160316AS_full_b1_s1_v1
ST3160316AS_full_b1_s1_v2
ST3160316AS_full_b1_s1_v3

The best type of backup to have is one that includes all partitions including any hidden partitions. Figure 4 and 5(inside the Link E2 reference) illustrate the disk mode backup which includes all partitions. One of the most frequent new user mistakes is that they backup only the Drive C which is usually not sufficient to restore to a new drive. It is best to backup all partitions.
