How to recover incremental backups properly ?

Does the first full backup exist? Sounds like the app is telling you it does not exist or it cannot find it. Where are these backups stored, external USB drive?

hey,
yes it is an external USB Drive and yes the full backup still exists, I can acces those files by manually entering the backup with acronis. Just entering is easy, however, recovering 800GB is way harder. At the moment, I am trying to recover all 3 backups manually but I dont know whats going to happen with those files, if they already exist. I started with the latest backup and acronis recovers the middle one right now. I keep you posted but some advice would be nice as well.

The files should be numbered such as
Full_B1_S1_V1
Inc_B1_S2_V1
Inc_b1_S3_V1

The full should be restorable as standalone.

Selecting 2nd Inc S2 will restore Full plus Inc S2

Selecting 3rd Inc on Inc S3 will restore Full plus S2 and then S3.
If S2 does not exist, then S3 backup is not restorable and has no value.

Great thanks, I´ll try it that way.
Does it matter that my backup is a file backup and not a partition / drive backup ?
When I backup my data, I wasnt able to choose partition backup , so I did the databackup instead.

I bought a new pc and formated the drives properly and its now working as "partition backup", so you dont have to take care of that problem as well.

A restore of a file backup will not be bootable, but may be bootable if the disk restored was bootable prior to the restore.

Which version of True Image?

Its 2014 and its just for data and not the OS.
The C partition was able to get backuped properly with the partition backup. Hence, everything is fine.

A review of my signatgure item 2A could be of assistance.
Also a review of this next link can help.

I dont have much time right now but I am going to take a look at that later, thank you.
In the meantime , I did some recovery again and I am just confused ...
My "problem" : I tried, as you said, the

"he full should be restorable as standalone.

Selecting 2nd Inc S2 will restore Full plus Inc S2

Selecting 3rd Inc on Inc S3 will restore Full plus S2 and then S3."

-Version of how to recover my data.

I started with the Backup from August 2014. Suprisingly , this backup ( or my harddrive after the backup was completed) contained pictures I definetly took in 2015. How is that possible ? Its quite annoying to deal with this "problems" every time I do backups.

I just checked wether those files are in the backup (before recovering it) and they are !
Its very ironically because I named the folder "bla bla 2015" and Acronis says "August 2014".

Why does the backup contain pictures from the first incrementel backup but apparently not from the second ?

Note the definition.
If you take Full on Monday
incremental on Tuesday--contains all disk sector changes that occured after the Full but before Tuesday Inc.
Incremental on Wednesday-contains disk sector changes that occurred after the Tuesday Inc backup and before the Wednesday Inc.
Neither inc duplicates any data as the backup only contains the changes that occurred since last inc backup.

Ccomparing incremental and differential type backups,
the differential type backup contains all changes since the last full.
so a Full followed by Tuesday Differential and then a Wedesday differential.
Both differential would contain all changes that preceded the backup, so Wednesday differential would include Tuesday,

The actual dates of the tib file should indicate the date/time created.

Thanks for the explanation.
So if I backup Tuesday incrementel, the Monday .tib is altered and the Tuesday changes are added ?
Thats how I understand it and my own case prooves my theory.

Could you explain this sentence to me "Neither inc duplicates any data as the backup only contains the changes that occurred since last inc backup. "
I dont understand it because of the neither at the beginning.

The neither comment could have been worked better.

Clarification:
The Full is unchanged. It has not and will not be changed. It is standalone. If only full restored (without inc involved) , the full will be restored as it was at time of creation. Restored Disk will be same content as date/time of Full tib file.

The data contained in first incremental is any disk changes that occurred from tib file date/time of the full to tib file date/time of the first incrmental.
If first incremental chosen for restore, the Full will be first automatically restored followed by the subseqent automatic restore of the first incremental. Restored disk will be of same content as existed at creation date/time of first incremental.

The data contained in 2nd incremental is any disk changes that occurred from tib file date/time of the first incremental to tib file date/time of the 2nd incrmental.
If 2nd incremental chosen for restore, the Full will be first automatically restored followed by the subseqent automatic restore of the first incremental followed by the automatic subsequent restore of the 2nd incremental. Restored disk will be of same content as existed at creation date/time of 2nd incremental.
By selecting a specific file for the restore process, User has a choice of choice of
Selecting and Restoring full only.
Selecting and Restoring first incremental which will auto include the prior restoration of the Full first. Or,
Selecting and Restoring 2nd incremental which wil auto include the prior restoration of the Full, followed by the restoration of the 1st Inc, followed by the auto restore of the 2nd incremental. It is not possible to restore the 2nd incremental wiithout the program auto restoing both the full and first incremental first.

Following a restore, the restored disk will contain the data put there by the last restore process.

Thank you very much for your thoroughly written explanation.
However, I still have questions.

As I said, I recovered the full backup from 2014.
It contains data from 2015. It even contains data from 2015, when I check the files manually by using acronis.
I can give you a screenshot if you like. The backup which has been created in 2014 , definetly contains pictures from 2015.
Therefore, executing the first incrementel backup has to change the original tib file. Otherwise I cant explain why this happened.

2. question, is there a difference in restoring file / data backups and partition backups ?
The question is related to your explanation of how the backups is restored. Is the same recovery method used both times ?

A partition restore would overlay any existing data and assume only data that is contained in the restored tib file.
A file restore would add to or increase the existing data already on the disk to include the newly restored data.

So yes, if the restore is a file type restore, you are basically dragging a copy of the file from inside a backup onto the storage disk.
If a copy already exists, the new copy will(may depending upon restore rules) replace; or if no copy exists, the new will add new content to the storage disk.

My comments did not relate to a file type restore.
