backing up lucent and cms

[helpdesk2005]

hello everyone - i am using dds4 tapes that were used to do cms backups. I am wondering what the commands are to do the backups and if it will bring the system down when i do them and for how long.

The dds4 tapes used for cms backup have 20 gigs on them and wonder if it is good enough for 2 days worth of data. how can i read this? is this done through the software that came with the tape drive i guess? thanks.

log in to CMS via root. at the command prompt type cmsadm
choose option 3. IF you have the newer release of CMS you dont need to take the system out of production. (r11, and newer i believe)

i have an r11 - i was told that this would bring the system down when i do a monthly - for say about 20 min? is there any way to read what is on my tape? i have the tape that came with the system - think it's sun's hardware - not sure what software will do this or what the command is. thanks.

The CMSADM option 3 backup will not take the sytem down. It does limit some functionality of the system, but it is still operational.

Not sure about the tape. Im sure you need to do some sort of unix commands to see whats on it. ie. cat | more \dev0\blah\blah\blah

Something like that.

When you run the CMSADM backup, you will continue to collect data and all Supervisor users that were already logged in will continue to be able to pull reports. The system will not allow any new Supervisor users to login until the backup is over.

A few words of caution about doing backups while the CMS is collecting call data. As I understand it, tables that are being written to by the CMS are not backed-up and the CMS will slow down considerably due to the amount of disk activity associated with the backup.

Just to clarify; there are two different types of CMS backup:

cmsadm which is available through the cmsadm menu as mentioned above.

cmsmaint which is accessible through the CMS menu under the maintenance tab. This backup only writes CMS data to the tape, not UNIX/Solaris files.

Both of the above backups will provide you with the estimated number of tapes required to perform a backup.

If you want to check your CMS daily tapes (with CMS data) you can run br_check located in /cms/bin

CMS admin backup backs up system files on Solaris. No users can login once this back up has started (we are on R11). To verify files written to this tape run this command from the unix prompt:
nohup cpio -ivct -C 10240 -I /dev/rmt/dev# -M
"Insert tape %d and press Enter" | tee

dev# is your device (usually rmt0)

In my experience the monthly backup usually takes between 30 mins to an hour.

thanks guys for the feedback. reallyrotten the "Insert tape %d and press Enter" | tee - is that just the step for me to insert the tape and do i need to enter some other command after that? thanks.

The command should prompt you to enter the tape, if that part of the statement doesn't work, just leave the "Insert tape %d and press Enter" out of the command.
