Differential backup, full backup disconnected from chain

For future reference, from inside the specific task, if you click the gear wheel, there is a MOVE option there.

Here is also how to delete backups from within the menu.

In order for the diff files to be of any value, they must in the same folder as the "original" full backup.
If you want to retain the full without the diff files, then the full can be stored anywhere for later recovery use as it is standalone with no dependencies.

If all together, You can try to regain their connection.
One thing to try would be to from within the program, choose the Browse for backup option(top menu) and browse to where the alll the files are currently stored. Highlight all and choose the "Add to backup list" option.

Then examine each of the backup tasks to see if the files are back together in one group. The adding to list opiton may put them into a new group so look at all the groups. From within each task, if you click the gear wheel and choose Recover, this should open up an Explorer window to display all files associated with the listing--just as shown in the delete illustation above.

Another opiton would to try the validation from their current location. but you will have to respond to all the prompts as it is lookiing to find all pieces. Some of the prompts will be to where is the files and you will have to point to them.

The current backup task is useless. Either change to a non-scheduled task or use the option to "Remove from list"option also found from inside the task listing of options.

Set up the new backup scheme using a Custom/Differential scheme similar to what you see in signature link 2 below and specifically illustration 11-Diff. Do read the text associated with the 11-dif illustration.
You can change the 6 and 4 to fit your storage availability but do select the "store x recent version chains." T
If you select a full after 6 diff, then each chain is 7 files.
If you choose "store 2 recent version chains, the you would be keeping the last 14 (7x2) files before automatic 9cleanup) deletion would begin.

Thanks for your help. So far, I've not had any luck recovering the differential backups. Looks like I might have messed things up too much for recovery and will need to bag those backups and start from scratch.

You could try one more thing.
With TrueImge closed.

Use Windows Explorer and Move (not copy) the full and the one diff you are trying to restore.
Move them into a new folder on the same disk so the move will only take seconds.

then move the remaining diff into another folder. The purpose of all is to move them to places that TrueiImag e has not been.

Look at your main listing of task on the main screen. Is there any tasks you really need?
Assuming no as what we are doing does not affect other backups.
-------
Next, we are going to clear the tasks and delete the history.

Next, Use Windows explorer find the Acronis folder named DATABASE
Inside that Database folder is a file named ARCHIVES.XML
Rename that file to OLDARCHIVES.XML
When the program restarts, it will be recreated with no tasks.

Next, open TrueImge and if you have any tasks listed, use the option in upper right corner (or inside each task)
and use the " Remove from list" all the still listed tasks. Once that is done.

Restart True Image and at the top of menu, click on "Add Backups" and click on the "BROWSE"
Browse to the folder containing the full and single diff.
Highlight the two files and click the option to Add to Backup list.
Once you have the backup task appearing on the screen.
choose the Recover option.
and see if you cannot Recover the entire full plus the diff listed.

You will probably need to work your way past some errors messages.

Edit:
Once you have the 2 files in their own folder, without doing all the other steps, you can also boot to the TI Recovery CD and do the recover of the diff or files only when booted from the CD. Work yolu way through the error message but a restore shouold still be possible.

I was able to recover the original full backup and the last successful differential. I don't know if there's a way to add some of the other differentials the same way, but I could probably get by with at least the two.

Thanks so much for your help!

You should be able to place all your diff with its original full into a single folder and then use the CD to perform a restore by choosing any single diff selected.

Understand when restoring a diff, you only need 2 files and only 2 files are restored. First the full is retored and then the single selected diff which contains ALL the changes which have occurred since the full was created. In other words, restoring #4 if it is the most recent puts your system back to exactly where it was at time of #4 diff backup.

Diff #2 does not contain any files not provided by #4 unless you deleted some files after #2 was created, then restoring #2 would contain those deleted files.

Again, thanks for all of your help!
