You are stuck with some kind of real time mirroring then. There is no backup solution that doesn't have at least a little lag. There are also socalled 'bare-metal' solutions such as Acronis, but in some sense, they are also a form of mirror/softupdate/journaling that may cost you possibly more than you want - given what you say above and are still vulnerable to a physical disk failure without additional backup and if you have to revert to one of those backups, then you have that lag loss. A mirror of a checksumming raid with periodic backups is probably the best you can get without getting in to huge money. The only question is your backup media. Tape is the old standby and still works, but takes a long time. Additional large disks are becoming popular because they are fast and easy but can get expensive when the dump takes more than one for a full dump. ////jerry > > So many experts here in this mailing lists can suggest their techniques > for a full system recovery(& backup solutions) after the crash without any > data lose. > > Your kind responses will help me lot > Thanks in advance > KK > > _________________________________________________________________ > Post free property ads on Yello Classifieds now! www.yello.in > http://ss1.richmedia.in/recurl.asp?pid=220 > > _______________________________________________ > firstname.lastname@example.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
