[Cisco] Archive error

This feature was introduced into Cisco IOS Release 12.3(4), the Archive command enables the administrator to configure snapshots of the configuration files.[inspiration here]

On a 3750 Switch, I bumped into the following error:

%ARCHIVE_CONFIG-4-ARCHIVE_SKIPPED: Archive of router configuration was skipped due to a previous initiation.

I also tried to save a copy on the switch, but still, the archive didn't worked:

BEFORE:
switch#show archive
The maximum archive configurations allowed is 14.
There are currently 1 archive configurations saved.
The next archive file will be named flash:/ARCHIVE-<timestamp>-1
 Archive #  Name
   1        flash:/ARCHIVE-Mar--1-02-01-51.358-EET-0 <- Most Recent

switch# archive config
Mar 31 11:55:23.016 EET: %ARCHIVE_CONFIG-4-ARCHIVE_SKIPPED: Archive of router configuration was skipped due to a previous initiation.

AFTER: (the same result)
switch#show archive

There are currently 1 archive configurations saved.
The next archive file will be named flash:/ARCHIVE-<timestamp>-1

There seems to be 2 workarounds: one that solves the problem after a reboot, but you can figure out on your own that reloading a production device in the middle of the day is not exactly dream hack.

The second one assumes to erase and reconfigure the archive configuration, and so I did. And IT WORKS. You can see the results bellow:

switch(config)#no archiveswitch(config)#archive
switch(config-archive)# log config
switch(config-archive-log-cfg)#  logging enable
switch(config-archive-log-cfg)#  logging size 500
switch(config-archive-log-cfg)#  hidekeys
switch(config-archive)# path flash:ARCHIVE/
switch(config-archive)# write-memory
switch(config-archive)# time-period 10080
switch#show archive
The maximum archive configurations allowed is 14.
There are currently 1 archive configurations saved.
The next archive file will be named flash:ARCHIVE/-<timestamp>-1
 Archive #  Name
   1        flash:ARCHIVE/Mar-31-12-05-16.835-EET-0 <- Most Recent
