cksum & md5sum fingerprints change after tar...HELP!!!
I've been testing our backups here at my office. After I write the tar file to the tape drive and remove it, the cksum & md5sum are different. I tried small files at first, with cksum it was different everytime.
If I turned hardware compression off on the st, the md5sum came up the same on a small file. When I tried our 5.5GB tar file, the md5sum came out different. I untar'd the file and pulled everything out of it, as far as I could tell, everything's the same. Should I be alarmed by this?
The only differences are this, the original is named nightly-backup.tar and located in /backups. After it's writen to the tape, it's renamed to lastweek-backup.tar. I pulled the original off the tape and stored in /backups/restore as nightly-backup.tar. Will this cause the differences?
This is what I get from an md5sum of the two:
This is what I get from a cksum of the two:
251230307 5562952704 lastweek-backup.tar
1523033174 5562952704 nightly-backup.tar
I tried renaming the files so they'd have the same name, just different location, and the numbers still don't match.
Any help is appreciated.
I did a search before posting and couldn't find anything helpful, but I may not know what it is I'm looking for...
