At this moment my server is backed up on a HP Colorado IDE tape drive (5Gb Compressed).
Last night I was viewing the logfiles in the server manager and all of the last week backups came out with a message "no more space left on device, backup aborted" ???
Is there a command to erase an entire tape with flexbackup, and can this be done before every backup.
The servermanager says there is 4 Gb of data on my server, and the tapes I'm using are 2,5 Gb native and 5 Gb compressed.
Looking forward to your reply,
Best regards

Yes, I did but the command "flexbackup -newtape" takes about 5 seconds to complete, so this can't be a full rewind and erase.
I also set used the commandline that flexbackup always will perform an erase before a backup.
I've also moved 2 Gb of data back to my desktop in order to reduce the data on my server so tonights backup should work because the the entire amount of data is now 3 Gb and it's a 5 Gb compressed tape.
More news tonight.
Best regards,

When tape manufacturers make statements like "2,5 Gb native and 5 Gb compressed" they are assuming 2:1 compression. If your data contains lots files that are already compressed (eg, jpeg, mpeg, etc) then the 2:1 assumption won't hold and the backup image may be bigger than the tape can hold.
