How to delete specific file(s) from backup set.

Thread needs solution

Okay. I have a backup job which does full + incrementals.

There are some files (I'm talking about backed up "content" files, like pdf or doc. I'm not talking about the tib files.) that I want to delete from all of the .tib files in the backup set.

Is that possible? How?

If so, will the data still "be there" in the tib files? In other words, maybe only some "pointers" to the files are deleted so that it looks like the content files are gone, but the content file data is actually not touched. If that's the case, is there a way to "securely erase" that data? Maybe I would need to do something like "decompress" and then "recompress" the tib files?

Not 100% certain what you are envisaging. However, the security model used by Acronis is that *.tib files cannot be edited. (Many years ago there was an option to create backups as *.zip files which could be edited but that disappeared about version 10.)

The only way to have a backup excluding the files would be to recover the files, delete the files that you do not want backup and then create a new backup. If the files are in directories only containing such files you could exclude them from the backup task.

Chris, welcome to these public User Forums.

Sorry - there is no way to delete specific files or other content from a .tib archive once created short of deleting the whole .tib file.

.tib files are created as 'Read Only' files, you cannot decompress / recompress them.

If you do not want specific content in your .tib backup archive, then you need to exclude that content when creating the archive by using the Exclusions options (for Disks & Partitions backups) or by not selecting those files / folders in the Source selection panel (for Files & Folders backups).

Your only other option would be to restore the contents of the .tib archive to a spare disk drive, delete the unwanted files, then make a new backup archive of that drive contents.
