[Wylug-help] Scriptable FTP, creating remote archives

[Christopher McLean]

Key based ssh, with tar output pumped over the connection? something like;

tar -czfv - <LVM SNAPSHOT> | ssh root at dumpserver.nixcraft.in "cat > /backup/<LVM SNAPSHOT>.tar.gz"

if you are up for it, you could most likely pump the lvm snapshot output directly to tar and never have data hit your local filesystem. 

I hate backups and as a rule of thumb remain paranoid about them, so general caveats of YMMV/not my fault/I didn't do anything apply to the above :)

| All,
| 
| I've just moved a DB-based app of mine to a new dedicated server and I
| got 100GB of FTP backup space as part of the deal.
| 
| The backup plan is to:
| 
| 1) Flush and lock the DB tables
| 2) Create an LVM snapshot (instantaneously)
| 3) Unlock the DB, allowing the app to continue running
| 4) Create an FTP archive of the current state
| 
| For a variety of reasons, it'd be preferable to create an tar archive
| on the remote box, but I can't figure out how to do it non-
| interactively.
| 
| The ancient command line FTP client can do it as follows:
| 
| > put |"tar czf - somedir" archive.tgz
| 
| ...but my usual choice for scriped FTP, lftp, doesn't understand this.
| 
| Anyone got any ideas?
| 
| Cheers,
| 
| James
