What is the meaning of the leading 11 charcaters in each line of the Last Log View ?

For example, the leading 11 characters in a number of my BIT snapshot logs are: cf...p..... Where is the meaning of these characters defined/explained? I can't se any information in the help file, the user documentation of the FAQs.

File deletions : how does BIT handle them?
by LateJunction Dec. 6, 2023

A significant number of the folders which are 'included' in one of my BIT profiles contain files of which some might be deleted after the first 'full' snapshot is taken. Examining the contents of the files created by BIT within any snapshot, I do not immediately see how BIT defines a file as having been deleted since the previous snapshot. So what prevents BIT restoring a file which has validly been deleted since the previous snapshot? Any restore operation must start with restoring the first, 'full' backup and then restoring, in date/time order, the subsequent incremental backups. This will inevitably restore the deleted file, which I might not want. I cannot specify to BIT that it is to restore backups that were created only after the file deletion, else the majority of the files in the initial, 'full' backup will not be restored. So, how is file deletion handled?

Why does BIT make incremental backups containing files which have not changed?

One of the profiles I have created backs-up a folder whose contents are important and which are subject to a lot of changes. I set the backup interval in the profile schedule to be 30 minutes. Unusually there have been no changes in this folder in the last 24 hours, but BIT has created an incremental backup, on schedule, since then which contains just a single file - the same file every time. It is not a file I can change because it is password protected and I do not have the password. I have compared every incremental backup version of this file with the original, using the diff command. No change is detected in any of the incremental backups. Why it BIT selecting just this one, unchanged, file in each incremental backup?

Modification of a profile: how does BIT handle this?

If I edit a profile - particularly if I change the specification of Includes and/or Excludes, after BIT has created the first, full, backup, how does BIT decide how to change the list of files it will handle in subsequent incremental backups? Surely a restore process will end up creating a restored set of files which differ to the original - won't it ? So, should a change in the profile require another full backup? If so, how many of the existing backup snapshots (full plus incremental) be deleted ?
