backup confirm via tar possible?
 

Ran into an issue where there was a corrupt tar and nothing to do except revert to an even older one. Naturally I am then asked, can you confirm via crc or something that a tar was successful?

I wish to tar / gzip some files and folders, will do them seperate, some are small, others can reach 5-7GB, but is there any way to verify aside from listing the contents that upon a tar completion that everything was fine?

Thanks.

Use the -W parameter to verify after backup.

I would recommend testing the ability to restore from a backup at regular intervals. No matter what operating system or backup software you use, this is the only way to be reasonably sure that your backups are good.
