Thanks Subhro dhaneshk k sat at his 'pewter and typed on 09/21/07 14:39: Hi , subhro, i agree with you , I need a clarification The backup should be the uptodate one , so in case of a disk crash (permanent crash) I need the backup upto the last moment , so is ther any cheap tools , to do it , so i can save the backups to another desktop pc synchronously (I mean any mechanism for backup through online ie ; ssh OR VPN or like that ) (not manual backing up at each moment) can you tell the exact solution . If I am using rsync , I can only do it by a crontab , even though at a specfic time only the cron run , if crash occurs after this time then the data after the cron will lose , so which is the right cheaper solution ?

Hello DharneshK, You can try to create a Mirror using RAID. You can either create a software or a hardware (recommended) managed Mirror. In case of a disk both are software. while the software one you talking about is gmirror - very portable and easy to use contrary to BIOS-based hardware one. and with gmirror is very easy to take whole disk snapshot ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

raid is a good solution for avoiding data loss due to hard disk failure (at
different rates depending on the raid type ). But it wont help you if someone
accidentally or on purpose delete files. Raid will happily replicate the
deletion across all your disks :)
Raid , fail-over solutions and the like go hand in hand with backups, each
case needing it's own analysis : server/s setup, data, frequency of change of
the data, how fast do you want to recover it , budget will (well, should :D )
all affect your final decision.
Whatever path you go down by, make sure you test the getting the data back and
the server back online step ;) it's too late by then to realise you should've
backed up /etc and /var/ , for example.

Re: Cheaper backup mechnism for a server
Hi ; A general question pls excuse me can any body suggest a backup mechanism for a server machine , which has a web portal , email server ,PgSQL database 4GB size , DNS server, Mailman , and a mediawiki applications running in a single machine . Sounds like a fairly small server. Should be no problem backing it up. Can you suggest good solutions , for the server Backup mechanismso that I can restore all the data just before the crashing moment . Well, if you want just before the crash, you need some kind of mirroring or raid that makes a recoverable copy or stripe of your data. Backups will only restore from the point of the backup. I would suggest mirroring combined with frequent backups - daily. As for the medium, it depends on how much backup you need. Do you need long term archive copies - then use tape. If you only need to restore a recent backup after some catastrophic failure, then probably backing up to a large USB disk would be fine. Use dump/restore to do the backups. Organize your file systems so that stuff that never or rarely changes does not go in to your daily backup and by size so that if possible, one file system can fit on a single recording media - eg tape or disk or whatever. It is possible to have continuation media, but it is nice if you don't have to. jerry pls share your expertise , it will help me lot to secure my data in the server machine ..
