A safe like that is a good idea for local storage of backup media while it waits to go into the tape library or off-site. It's a bad idea for storing your entire archive. You really want your backups to be stored in an off-site location. Preferably by a company that has the right sort of secure archive facilities.

For what it's worth, I found Amanda unnecessarily complicated for my simple needs at home. I tried Bacula as well and it seemed easier, but not enough to make it worth it.

Re: Backup and FreeBSD/ZFS
If my memory serves, you're looking at something similar to taking a snapshot and then sending it to the tape device, so zfs send snapshot | (tape device access). This, IIRC, is functionally identical to dump/restore. The Solaris ZFS Admin guide is generally helpful (even as we live in the FreeBSD world).

Will going the Opensolaris route be easier? (I had hoped to be able to use net/istgt/ from ports, but I guess I could find a different solution to that problem in Solaris). Any pointers would really help me here. The storage backend will be on MFI arrays (set up with redundant striping + automagic weekly consistency checks of the arrays). //Svein - -- - +---+--- /\ |Svein Skogen | sv...@d80.iso100.no \ / |Solberg Østli 9| PGP Key: 0xE5E76831 X|2020 Skedsmokorset | sv...@jernhuset.no / \ |Norway | PGP Key: 0xCE96CE13 | | sv...@stillbilde.net ascii | | PGP Key: 0x58CD33B6 ribbon |System Admin | svein-listm...@stillbilde.net Campaign|stillbilde.net | PGP Key: 0x22D494A4 +---+--- |msn messenger: | Mobile Phone: +47 907 03 575 |sv...@jernhuset.no | RIPE handle:SS16503-RIPE - +---+--- If you really are in a hurry, mail me at svein-mob...@stillbilde.net This mailbox goes directly to my cellphone and is checked even when I'm not in front of my computer. - Picture Gallery: https://gallery.stillbilde.net/v/svein/ - -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.12 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAktpSlIACgkQODUnwSLUlKRvRQCcCKgCzTSCr9PVfyQ9cveGkuUd xTIAn2IWherBzlLTu/02CBLJMo34Ky2m =ruSv -END PGP SIGNATURE- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Let's just say that ... there's a reason I've invested in an autoloader for my home server (it will, among other things, hold about a terabyte of Nikon .NEF files if that means anything) //Svein - -- - +---+--- /\ |Svein Skogen | sv...@d80.iso100.no \ / |Solberg Østli 9| PGP Key: 0xE5E76831 X|2020 Skedsmokorset | sv...@jernhuset.no / \ |Norway | PGP Key: 0xCE96CE13 | | sv...@stillbilde.net ascii | | PGP Key: 0x58CD33B6 ribbon |System Admin | svein-listm...@stillbilde.net Campaign|stillbilde.net | PGP Key: 0x22D494A4 +---+--- |msn messenger: | Mobile Phone: +47 907 03 575 |sv...@jernhuset.no | RIPE handle:SS16503-RIPE - +---+--- If you really are in a hurry, mail me at svein-mob...@stillbilde.net This mailbox goes directly to my cellphone and is checked even when I'm not in front of my computer. - Picture Gallery: https://gallery.stillbilde.net/v/svein/ - -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.12 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAktpzMgACgkQODUnwSLUlKRRfgCgulZAvQN61uE6HIcuvxzkU2yS HaAAmwcHY6YYqoTYlw/R/KeWuy/9ferH =zHrR -END PGP SIGNATURE- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Re: Backup and FreeBSD/ZFS
Yes, I have three sets running that way, my home systems using a Dell 122 and a 5 rack config at work with a 7x200G Tandberg and a 48 slot 4U IBM beast. All are using the mtx changer scripts that come with Amanda. -glz --On Wednesday, February 03, 2010 8:22 PM +0100 Svein Skogen (Listmail Account) svein-listm...@stillbilde.net wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 On 03.02.2010 17:41, Goran Lowkrantz wrote: I have been using Amanda straight from the port, it supports both tar from snapshots if you need to be able to retrieve individual files from the backup and zfs send if recovery at filesystem level is OK.
