Manual backup tool?

Question

System administration

The essence of the problem: sometimes you need to make backups of several directories from drive A to drive B. It is planned to start it manually. the task is not to constantly overwrite the entire amount of data, since disks A and B contain actual data that does not need to be copied again (normal copying can also cope with this), but what it can’t cope with is deleting invalid data on drive B that is no longer on drive A.

Answer 2

Regular windows backup mechanism.

Answer 3

Unfortunately, you did not write for which system it is needed, but I would follow the principle (using PowerShell if possible):
1. Get a list of files from drive A;
2. We got a list of files from disk B;
3. Array with file names B - A = unnecessary files into a new array C;
4. Delete objects from disk B according to the list of array C.
Or take any backup system and make normal backups (having previously made a backup plan) of two types, full and incremental / differential at your discretion. Schedule and keep copies. And you will always have up-to-date information in a copy.

Answer 4
