I've been using tarsnap for about a year, and I'm pretty happy with it
overall. I've been noticing my storage usage (particularly on a couple
of systems) creeping up, so I took the time over a couple days (and it
did take that long on the higher-usage system) to nuke most of the daily
backups I'd been storing, in favor of one per month except for the most
recent 30 days.
I did manage to get my storage totals down a bit (29GB->27GB on one
system, 28->25GB on another), but in doing so, I racked up bandwidth
charges which would have paid for the storage charges I saved for more
than 60 days, and was also about 8x the total daily storage charge.
So, I'm wondering if I'm doing it wrong. :)
Basically, I have a script on each system I'm backing up that runs
tarsnap once a day on /, and I flag scratch partitions (etc) with
'nodump', so they don't get backed up. What I'm wondering is if there's
an easier/cheaper way to remove specific data from my daily storage
totals that I later decide doesn't need backup without having to delete
all archives between when that data was first backed up and when I
deleted it from the master... I don't see an easy answer, but perhaps
I'm missing something.
The other thing I wonder is if there's a less bandwidth-intensive way of
deleting stuff. I mean, it makes sense that bandwidth is used during
deletes, but I was a little surprised at how *much*...
Thanks for any input!
