comment Are encrypted backups a good idea?
Also, in most CTR cipher mode, a bit flip will only affect that single block of data. The rest of your backup should be just fine.

comment Can I access a ZFS Volume as if it were a file?
Also, anything is Unix is a file, including partitions. @ewwite's answer is what you want to do, but you could read it directly as a file.

comment Linux - How to tell which files are sourced at login?
Well yes, expanding the commandline to monitor that directory will show files accessed from it. I was wondering if you might have something that would tie to a given process. It occurs to me, though, that filtering the results afterwards probably makes as much sense.

comment backing up my linux server to my windows machine
Well, the easy way is to just rsync them. Bacula always appends, so you can only be out the last backup. The fancy way is to write one job per file ("tape"), and query the database for files that are marked "done".

comment Iptables ignoring a rule in the config file
Gnarly things are going on in your machine. It is suspect, and should be wiped clean and rebuilt.

comment backing up my linux server to my windows machine
Well, if he were talking about just keeping a copy of his home directory, I'd say rsync alone is enough. A straight rsync solution doesn't provide for increments by period, and doesn't provide a mechanism to dump MySQL without layering another scripting layer on top. While rsync will cut down on bandwidth like the Bacula + rsync method would, I feel in his case the complication may be worthwhile. I think he has both arguments in full and can just decide what works for him from here... he knows more about what he needs than I do. :)

He should run the storage daemon on the same machine he's backing up, and use the Windows machine to move the tape files that are done being written to.
