The only thing I'm not sure on is the -f option to amrestore The man page states: -f Do a rewind followed by a fsf <fileno> ... restore an image. I cannot work out what this represents (I'm sure it's obvious :)) I stabbed at it and just entered 1 and it seems to work ok. # cd /tmp/restore # amrestore -p -f 1 file:/path/to/tape/tape01 | tar -xpGvf - .
Without the -f option, amrestore uses the slow method to find the correct image: read header, check is this matches the pattern(s) given on the command line, if not, read and throw away the image. For a multi gigabyte tape, this can takes a while. Amrestore does normally NO rewind of the tape, so, the experienced Amanda administrators used "mt -f .. fsf 32" to quickly skip to image 32 on the backup tape, and then issues "amrestore". Much quicker. Amrecover uses "amrestore" behind the scenes too. And "amrecover" now can instruct amrecover to quickly do the same as those experiences admins. If you specified "-f 1", then amrestore just advances one file (=backup image), and then starts the slow scan as explaned above. If you have only one backup image, then you want notice the difference of course. -- Paul Bijnens, Xplanation Tel +32 16 397.511 Technologielaan 21 bus 2, B-3001 Leuven, BELGIUM Fax +32 16 397.512 http://www.xplanation.com/ email: [EMAIL PROTECTED] *********************************************************************** * I think I've got the hang of it now: exit, ^D, ^C, ^\, ^Z, ^Q, ^^, * * F6, quit, ZZ, :q, :q!, M-Z, ^X^C, logoff, logout, close, bye, /bye, * * stop, end, F3, ~., ^]c, +++ ATH, disconnect, halt, abort, hangup, * * PF4, F20, ^X^X, :D::D, KJOB, F14-f-e, F8-e, kill -1 $$, shutdown, * * init 0, kill -9 1, Alt-F4, Ctrl-Alt-Del, AltGr-NumLock, Stop-A, ... * * ...
