Backup solution with list of backed up files in db
I have CentOS server with 10 TB of storage (RAID 5). I am looking for backup utility, which could backup newly added files from one folder to external drive. The external drive has only 2 TB, so I need to replace it multiple times. All utilities I found check files physically on the external drive to find out, which files are already backed up. It works fine for the first 2 TB, but then I change the full external drive for new one and it would backup again already backed up files. Is there any backup utility, which has some internal db of already backed up files, so it does not check them physically on the external drive?
Thanks in advance for all answers.
