Hi
there,
I've not installed
Bacula as at the moment I use rsnapshot to maintain backups of data between my
two Linux hard disks and a few home clients. I'm thinking of switching but have
a few questions that the FAQ doesn't appear to cover.
1) Functionality
like Synthetic backups. i.e. imagine I have 300GB of data and my backup will be
going on a 400GB hard disk. My first backup is a full, then after that point
there will be incrementals. However - lets say weekly - I want to ensure that my
full image is current - but don't want to delete the existing full backup until
I'm 100% sure that the next one has succeeded. Netbackup calls these things
synthetic backups since it reconstructs the full backup and injects the
incrementals into it. Does bacula have this?
2) Backup
validation. I'm paranoid about data getting accidently corrupted. Having seen
some of the interesting things that disk drives can do - such as high fly
writes, not write but ack the client, etc - I like to verify everything I back
up. Is there a way of telling Bacula to check an existing backup to ensure that
the backup hasn't got corrupted. I guess I could md5sum the backup pool file? or
is there a built in way of checking that the pool files aren't getting
corrupt?
Thanks
Paul
