Moving to Version chain backup

Thread needs solution

Using Acronis True Image Build 6614 File backup
Because I have accumulated 60+ versions for my file backups I need to move to The Version Chain strategy.
My goal is to possibly have a full backup plus maybe 10 incremental versions. I understand there is a setup do
a full plus a set of incrementals and then start over. I believe there is a mechanism which will eliminate the
obsolete full/incremental set after a period of time.

My question for now is 1) if I delete the existing backups on disk will acronis realize what I've done or will it get confused.

2) Is there anything wrong with my interpretation of Version Chain capabilities?

I believe you would be better served if you used the Custom/Incremental backup scheme with automatic cleanup.
Cleanup either based on "store no more than x version chains" or based on elaspsed days. Two examples are below.

Link based on elapsed days.

Figure 11-Inc: Example of custom/incremental backup method settings
If using incremental type backups (which is full + X Inc), the 11-Inc is my recommended method. Change the 6 or 4 to fit your available storage.
These automatic cleanup settings will provide for automatic deletion of the oldest backups after the "Store no more than X number of chains" quota has been reached.
In this example, deletion of oldest backup will occur immediately following creation of backup #29.

Allow space for 1 more full backup in addition to "Store no more than X number of chains" as the program will NOT delete the oldest full until its replacement has been successfully created.

In this example, one chain or one recent version chain =1 full plus 6 inc or 7 files per chain.
If keeping 4 recent version chains (4 chains of 7 each) retention would be 28 files. Deletion of oldest chain will occur after backup 29 (full).

Also understand the limitations/risk factor of incremental backups.
If one inc backups gets corrupt or accidentally deleted, all newer inc are worthless so avoid excessive number of incremental backups. Always maintain a full backup set which are current This explains why keeping a reasonable number of x "recent version chains" can be very important. Keeping a high number of incremental is a high risk factor to your backup data and should be avoided.
For a better understanding of the differences between Inc and Dif as it relates to the safety factor, review this link.

When restoring an Incremental backup, select the specific Inc file to be restored and all preceding Incremental files plus the full backup base must be present and will be restored (multiple files required).
