Re: make_tape_recovery , Number of Archives to save ?

Hi,

This option does not mean it will create two successive recovery tapes. It is going to keep two configurations saved by the make_tape_recovery process under /var/opt/ignite/recovery directory with the date,time format. When run next time, it will remove the oldest configuration directory.

It is quite useful for make_net_recovery as the archives are actually stored on the ignite server, than for make_tape_recovery. check_recovery which is not available now used to use this information to tell the administrator if there is a need to run make_recovery (old utility) again.

Thanks!

Is there any way of knowing at the beginning how many tapes it will use? I added 2 filesystems to it and want to know if I should stick around to pop in a second tape.

NO there really isn't a way to know how many tapes it will need. You can do some guesstimating yourself though. Look at the sizes of the stuff you are backing up and then look at your tape size and figure from there.

Be sure to keep in mind that a lot of the tape manufacturers emphasise the compressed (usually a 2:1 ratio) capacity of the tape. Depending on what you are backing up though, you may not get that much on a tape. I always figure with the native (non-compressed) amount and if I get more on a tape, I'm lucky.

There is a better way than tha suggested by Patrick.

Check the list_expander options:

# /opt/ignite/lbin/list_expander -?
usage:
OPTIONS: [-f file] [-d] [-l -|file [-S] [-C]] [-s] [-v] [-?|h]
-f file Used to specify the content_list file to use.
-d Used to request list of disks/vgs and indicate PARTial or FULL inclusion.
-l -|file Used to request list of files, "-" to stdout.
-s Used to request cumulative size of files.
-S Used to request size and date on each file in list.
-C Used to request checksum on each file in list.
-A Used to indicate that all files on each selected disk or volume group are included. If this is in conjunction with the -d option, then sets inclusion to FULL.
-v Used to specify verbose output (show lvols in disk/vg list).
-?|h Used to show the usage of this program.

# /opt/ignite/lbin/list_expander -f
/var/opt/ignite/recovery/latest/archive_content ???s
