Hi!

What will happen if I run out of space, will that somehow corrupt the
backups? Sorry if I'm asking a question that has been answered
already.

Thanks for a great piece of software!

Sincerely,
Markus Hedlund

Hallo, Markus,

Du meintest am 29.03.11:


What will happen if I run out of space, will that somehow corrupt the
backups?


No - the existing backups remain unchanged, at least those of the lowest
interval (p.e. "hourly").

The higher intervals run on: "daily" is rotated, "weekly" is rotated,
...

Viele Gruesse!

Even if we run out of space mid-backup?

Thanks,

No - the existing backups remain unchanged, at least those of the
lowest interval (p.e. "hourly").

Even if we run out of space mid-backup?

The program rebuilds the old backups. Just take a try - it doesn't hurt.

Because it interrupts the flow of the conversation and makes it harder
to read.
Why shouldn't I top-post?

If you run out of space during a backup, you may end up with a dodgy
daily.0 (or whatever your most frequent backup is called). And this
dodginess may slowly spread, as that backup gets copied to daily.1,
daily.2 etc. But you'll see from your logs (which you do, of course,
read) that that happened, and so be able to rectify the problem before
it becomes severe.

In this, rsnapshot is the same as any other backup scheme.

sync_first with the recommended setup avoids the problem
pretty well: if sync fails, the rotation simply doesn't
take place, all old backups remain intact.
The "dodginess" cannot spread, backups are merely
suspended until you make room.

I guess I should put the log files on a separate partition. Otherwise
the logs won't be stored.

Rectify the problem, is that deleting the affected backup? Can
rsnapshot handle a missing backup? daily.0 daily.1 daily.3 for
example.

That's good to know. Does rsnapshot check if there's space available,
regardless of sync_first?

No - how should it check?
It doesn't know how much space it will use.

If nothing has changed it needs no additional space.
If all has changed it needs the whole space.

[...]

[Top-post repaired]

I guess I should put the log files on a separate partition. Otherwise
the logs won't be stored.

???
The place of the log file is defined in "/etc/rsnapshot.conf" (or
whatelse you may define as config file). And I hope that you have
included "/var/log" into your backup.

Rectify the problem, is that deleting the affected backup? Can
rsnapshot handle a missing backup? daily.0 daily.1 daily.3 for
example.

Why should it? The programm rotates the backups when you tell it to
rotate them.

Why don't you test your ideas? It's a very simple job to look for a
small partition and then put a lot of "rsnapshot" backups into this
partition.

----------------------

Please don't top post.
Please don't full quote.
Thank you!

If you use the mail program from googlemail: that's nasty crap. Take a
better program. Thank you!

Indeed.

If the problem is lack of space, then deleting a backup would only be a
temporary fix. A permanent fix would be to add more disk space.

That's not quite true. It doesn't need any extra space for files, but
it will still need space for directories.

Right. But the beauty of sync_first is that the sync call
in a sense acts as such a check, too: if it runs out of
space it fails before any corrupting rotation has occurred.
